Don't know what to make of Gooch (god.. i love Scrubs!).. not getting Raj a girlfriend was always the thing with BBT.
Raj's bit was originally not being able to talk to girls, and had nothing to do with the possibility he might be gay (in fact, the psychological fear of talking to women leads to the conclusion that he is NOT gay, he simply fears them). It was either the season 1 or season 2 halloween episode, but he actually ends up hooking up with a girl at Penny's party, and when he wakes up the next day he is unable to talk to her. She thinks he is a good listener!
