LOS ANGELES ? ?Is it proper to Twitter during sex?? That?s one of the latest howlers from Robin Williams in our recentpress con with him.

As we?ve written before, Robin is atypical of comedians?he is hysterically funny in person, quick to the draw, and always ?on.? Some comedians are actually so serious and taciturn in real life that they bore us to tears. In Robin?s case, laughter only ceased when he answered a reporter?s question about how his friend, John Travolta, was doing since the actor lost his son, Jett.

Robin stars with John in the family comedy, ?Old Dogs.? He also topbills ?World?s Greatest Dad,? a comedy-drama written and directed by Bobcat Goldthwait. In it, Robin portrays a single dad and teacher who aspires to be a rich and famous writer, and later learns that the things you covet most may not necessarily bring you happiness.

Divorced from Fil-Am Marsha Garces Williams, Robin talked about their kids, Zach, Zelda and Cody, and how he was adjusting after the separation. And, here?s Robin?s answer to his own question if it?s apt to ?tweet? during sex: ?I don?t think so.? Excerpts:

How have you been feeling since your heart surgery?

It?s weird. After you go through heart surgery, you get very emotional. For a while, I felt that, instead of a valve, they gave me a tiny vagina. Actually, I got a bovine valve, which has made it hard to eat meat, because it?s like, ?You?re one of us now!? After over four months, it seems to be working. When you?ve just had open-heart surgery, you do get this idea of a second chance.

Letters

I was thinking, if they offered me a mechanical valve, I could get the new Apple iHeart. It comes with applications?50,000 songs in the heart rather than out. I?m cycling again. It?s that thing?it?s Robin 2.0. You come back from the surgery thinking about how grateful you are for everything, like breathing and appreciating all the people who wrote you letters.

It would be great if you could have cash for clunkers like old organs. Or, maybe go to that rabbi in New Jersey who sells livers. ?How much for the heart??

How is John Travolta doing?

I haven?t heard from him. I sent condolences, and I hope he?s well. Losing a child?I can?t even fathom that.

What was it like working with John in ?Old Dogs??

He?s fearless, and he?s the sweetest, funniest and kindest guy. If you saw ?Hairspray,? you know he?s not afraid to be a big woman, and neither was I. It was a blast, because it was a great comedy pairing. I would try something and he would play off it. It was like jazz?we riffed together pretty well.

The movie?s basic running joke is about these two older guys raising two children. John?s character is always hitting on women. My character is like, ?Oh, don?t do that!? He uses the children as cougar bait. You have to have a Range Rover and two kids?then, you can trap nice cougars. You have to bring a vial of Botox to sedate them.

How are you coping with the divorce?

Quietly. I?m spending a lot of time with my children.

How are the kids adjusting?

Kids adjust pretty quickly as long as you?re straight with them. They?re old enough to know what?s going on.

Zach is married and living in New York. Zelda got her high school degree and has been acting. She?s done five movies. In several of them, she gets killed. I went, ?Oh, great.? In one, she played the concubine of Satan. I said, ?That?s my girl!? Cody is off to college. He?s a great writer, and I?m in shock.

As a parent, did you ever feel there were instances you could have handled better?

Yes, but it?s a question of time. Sometimes, you have to realize he?s your son, not your friend. And, for a while, there was a bit of my arrested development. I played games with them. ?Let me win.? Then, my son would say, ?Wait a minute, you are 50, and I am 10.? Or, Zelda once said to me while I was reading her a story, ?Don?t do the voices, just stick to the story.? I learn from them. I had a rough period, and I came back from that. I appreciate them more now, and they appreciate me, too.

Part of the drill

I like being honest and say to them, ?I can tell you about many things. You?ll make mistakes, and that?s part of the drill. You?ve seen mine.? They?ve been published, and there?s even a videotape if you really want to see for yourself.

I?m very proud of them: Zelda?s acting. Cody?s writing, and Zach is God. He does all sorts of different things?producing, writing, and I just say, ?Good luck!? But, the one thing that I always say to them is, ?Love what you?re doing, then people can?t stop you. It won?t be easy. But, if that?s what you really want to do, you have a fighting chance, rather than saying, ?I?m going to be famous!?? Oh, no. Good luck, because that comes and goes. It?s cyclical at best.

What are you looking for in a woman now?

Cougar? No?more of a mountain lion. Somebody who?s not afraid to mount the lion. Right now, it?s very quiet. I live in Northern California, where it?s even quieter. I can go out, and people don?t say, ?Oh, it?s you.? I can blend in nicely.

You went nude in ?World?s Greatest Dad.?

They had to shave me, and there were animal rights issues. We can make a nice sweater out of the pile.

Is it easier for you to do a nude scene as you get older?

It never gets easier to do a nude scene. I did one in ?The Fisher King,? where I was nude in Central Park. It was nighttime, so it was very cold. But, to do a nude diving scene is another matter. I suggested it to Bob because at that point in the story, my character is kind of shedding everything.
