Long time lurker, first time poster. I looked through over half of this thread before I gave up, so if these have been mentioned, my apologies...
If it hasn't been mentioned, I'm shocked. My jaw almost hit the floor the first time I saw it.
Jane's Addiction - Mountain Song. Girls dancing in diapers.
Don't think it has been mentioned, but again, apologies if it has. Spike's
1000 Ways to Die - Crib Your Enthusiasm.
My most salient memory. HBO's Real Sex - There was a segment about a German woman and her, I think, husband who was an AB. Showed a diaper change scene. My friend watched this in high school for obvious reasons. Was watching it one night just hanging out and I couldn't figure out how to react. Wanted to be like, "woah, me too!" Friend was like, "gross." Figured I shouldn't say anything ;-).
There was a skit show on MTV or Comedy Central that had a short skit at the end of a show that showed two guys carrying two guys in diapers and another guy says something like "Infantilism? I'm not in to that." I swear it was The Slate or Upright Citizen's Brigade. Something like that. Swear it was Michael Ian Black, so I think it was The Slate, but
can't find a reference.
