So I was watching It's Always Sunny in Philadelphia, specifically the episode "Frank Sets Sweet Dee on Fire" where the brother and sister try to get famous but they take ecstasy and join in a cable access viral video phenomenon that the gang agrees, they can't take their eyes off of.
This is the viral video. 4:00~ is when diaper time kicks in.
YouTube - Re: Doomtree: As Seen On TV pt. 2
It's not exactly a bad representation since the characters (under the influence of entheogens) were open minded enough to diaper up themselves haha
