Bill Cosby says he knows what it's like to feel a mother's curse when she cries out to a child, "When you get married, I hope your children act just like you?"

And apparently a lot of people in the capacity audience of 6,700 last night at Wolf Trap had felt it, too. The comedian, who has made a career of poking fun at himself as a father and husband, held a laugh-therapy session on the problems of raising children.

He thought the swing-era music of his parents was square. His father thought modern jazz sounded so bad that he threatened to destroy Cosby's hi-fi set. And now Cosby, who thought he'd be the hippest parent alive, is afraid to enter his oldest daughter's room and ask her to turn down the disco music.

Cosby has the rare ability to talk about every-day life and make it sound hilarious. Last night he did that with stories of a trip to the dentist and the perils of skiing and sky-diving.

If you've seen him on "The Tonight Show" recently, some of the stories will be familiar. But they can stand retelling.

Cosby started off his two-hour monologue talking about the emotional pangs of slipping into his 40s (he just turned 42), and he returned to the theme throughout the evening.

From the time he walked on stage wearing blue jeans, a Wolf Trap T-shirt and jogging shoes, Bill Cosby proved himself a comedian for all seasons - and all audiences.
