Raj: Hey, why didn't you invite him in the first place?
Sheldon: You don't know what it was like growing up with him.
Raj: I get it; I grew up with lots of brothers. My brother Adoot was especially mean.
Leonard: Really? I've never heard you mention Adoot.
Raj: Yeah, sure I have. He's the one who left the door open when we were kids, and my pet mongoose ran away. Stupid Adoot.
