A farmer walks into a bar with a horse. He says, "I will give any of you $1,000 if you can make my horse laugh."
A man yells, "I'll take that bet," and leads the horse into the men's room.
After a couple seconds, a loud braying laugh is heard from behind the door. The farmer screams to the man, "OK, I'll give you $2,000 if you can make my horse cry."
