There are two cows standing in a field.
The first cow says to the other, “I was artificially inseminated this morning.”
The second cow replies, “No way, I don’t believe you.”
The first says, “It’s true, no bull.”
A farmer friend of mine has just told me he’s managed to cross a cow with a chicken.
Sounds like a cock and bull story to me.
Why can’t cows join the police?
Because they refuse to go on steak-outs.
