Okay, fess up, EVERYBODY here thats old enough watched Pee Wee's Playhouse, and wel all know it :P
More to the point though, have you seen it since you "grew up"?
Few years ago, it used to air on ABC Family, and I started watching it again with my little brother. And, aside from the stuff I remembered, what did I see?
Good lord, the pure amount of sexual innuendo in that show is crazy.
I had no idea so much of Pee Wee's origins as an adult comic were actually allowed to make it into the kid's show!
Great example, Miss Yvonne and Pee Wee are doing the arts and crafts project for the day, how to make a book out of construction paper and yarn. Pretty normal fare. Until the shirtless portarican soccer guy in short shorts somes in to check up on them. Miss Yvonne lets rip with "Oh, <whatever his name was>, look! I made a book so you can keep track of how many times you score.... in soccer!"
I mean, big old pause there that made it pretty obvious to me NOW what the joke was, but it went right over my head when I was a sprout.
