AN INDIAN, A PRIEST AND A BICYCLE

An Indian and a priest are walking through the woods. The priest is teaching the Indian the English language, so he can be integrated into the "white man's society".
As they walk along, the priest sees a tree and says to the Indian,"Tree". They continue walking along and come upon a bush, and the priest says to the Indian, "Bush". They keep walking and eventually come out into a small clearing, where they come upon a man and a woman having sex. The priest is so upset, he's not sure what he should tell the Indian. The only thing he can think of to say is "man riding a bicycle".
The Indian then pulls out his bow and arrow, aims and instantly kills the man. The priest turns to the Indian and says, "What'd you do that for?"
The Indian replies, "MY bicycle!!"
