Did anyone catch last weeks episode of The Big Bang Theory (season 7 episode 21)? In the second to last scene Raj and his new love interest (I forgot her name but it's not Lucy) are going to watch a scary movie together and his girlfriend jokes that she was a nanny for 3 years and that if Raj gets scared she can change his diaper.
In another fairly recent episode all the guys are on their laptops ready for Comic-Con tickets to go on sale. Raj says he has to pee, to which Sheldon replies "Every year I told you wear a diaper" then Raj says "And I told you I get diaper rash." (see link below)
Raj's small bladder is the subject of several jokes on the show as well, but I don't think the character actually wears diapers (although Kunal Nayyar would look really cute wearing a diaper). Raj is my favorite character on the show , because they write him as being really emotional and kindhearted.
Just wondering if anyone remembers any other references on the show and what people think.
