In older cartoons when we saw an older character wearing a diaper it was because they were pretending to be a baby. I have seen two cartoons in the last few years where the character was wearing diaper just because he wanted to. one is an episode of sponge bob where Patrick admits he has been changing his on diapers for years. the other is the fairly odd parents where Cosmo admits in several episodes that he wears diapers. Do you know of any other cartoons where the charactor was wearing diapers for reasons other than because he or she was pretending to be a baby?
