Ha! So at this year's annual Del Close Marathon at the UCB Theater in NYC at 3:50-4:00am late Saturday/early Sunday (yes, ten minutes in the middle of the night) there's a short act called "Pie Babies" where grown men in diapers are hit with cream pies by a clown. That description isn't on the calendar but I saw it from a review of a previous year's marathon.

oh man, I would LOVE to do that, as long as i get a few square in my face, and maybe some pie in my diaper =3
