One day, a farmer walked into a bar and asked the bartender for the strongest thing in the bar.

"What's wrong, fella?" asked the bartender.

''Some things you just can't explain."

''Try me.''

"Okay. I was milking my cow this morning and I filled the bucket clear to the top. Then the dumb cow knocked it down with her left leg, so I grabbed some string and ties her left leg up. Then I milked her again and the stupid cow knocked it down with her right leg. So I grabbed some string and tied up her right leg. I then milked her again and the cow knocked it down with her tail. But this time I was out of string, so I decided to use my belt, so I tied it up with my belt. Just then my pants fell down and my wife walked in.''

"You're right," said the bartender. "Some things you just can't explain."
