there was a scene in the first episode of the Ted series where john (i think thats his name) and ted go to a bank to get rocky balboas mouthguard
in this scene the banker comes in and talks about how the super absorbent polymers or SAP made diapers thinner (this was set in the 90s by the way so this was when SAP was first introduced in adult and baby diapers)
it its implied that the banker is wearing a diaper and you could even hear the crinkle from the plastic and the bulge in his pants from the padding
then at the end of the scene it is also implied that his diaper leaked and needs a change (also attempting to take off his jeans in the distance to get a new pair)
