A guy from a city once went to go see his old collage pal who
lived on a farm.  One morning the city slicker got up early and
decided to fix breakfast for his friends family. 

By the time he got from the pasture to the hose his friend was
up so the guy from the city decided to show his friend what he got.
When he walked into the kitchen the farmer looked at him.  The city
guy's face was covered in a white liquid and he had a bucket full
of this white stuff.  The city guy said, "I milked the cow for you
this morning."

The farmer replied, "I don't have a cow.  I have a bull!"
