Many years ago a missionary took it upon himself to spread the Gospel among 
the indian tribes of the west.  

His first try was to win the support of the chief before approaching the 
tribe members.  He took the chief out of the village for a walk so they 
could talk.  

As they moved around he looked for common things to discuss in order to 
make a good impression on the chief.

As they neared a tree the missionary pointed at it and said, "Tree."  The 
chief repeated "Tree."  He then pointed to a bush and pointing said, "Bush." 
The chief repeated, "Bush."

As they came aroung the bush they came upon a couple copulating.  The chief 
said, "What that?"  The missionary was embarrassed so he said, "They are 
riding a bicycle."  The chief pulled out an arrow and shot the top indian. 
The missionary asked why.  The chief said, "He riding my bicycle!"
