My dad tells me I have no sense of humor when he tells awful jokes, but he sometimes tells a gem. Here's another:
A man was quite the drunkard and would drink away all of his income. His wife eventually became so fed up with his drinking that she had to take the matter into her own hands. She decided to put a dead cat into his liquor to scare him away from the stuff for good. One day when the man was away, the wife went out, found some roadkill, put it into his vodka and went on her merry way. When she came home she saw her husband wringing the cat over his head begging "Kitty, just one more drop!"
