Indian guy goes to his doctor and tells him that when in large open spaces, he feels really nervous when he sees white people. The doctor placated him by telling him that he is a-gora-phobic... yeah, if you don't understand that gora is a hindi word for white people, it really doesn't work. Thus far only one person has laughed when I told them the joke.
Meh, I made the joke up whilst walking over Hammersmith Bridge... I thought it funny...
