A guy walks into a bar and notices a horse standing over near a rear door. There is a sign below the horse reading: " Bet $5 and if you make the horse laugh, you win $1000"

The guy puts in $5. He walks over to the horse and whispers in its ear.

The horse starts laughing like crazy.

The bar pays off.

The same guy walks in a few nights later and there is the same horse. However now there is a sign that reads: "Make the horse cry and you win $1000"

The guy puts in his $5 and walks over to the horse. However, this time he doesn't whisper in the horse's ear but leads him out the back door. In a moment or two they return -and the horse is weeping tears.

Again the bar pays off. However, this time the owner asks: " How did you do it to first make the horse laugh and the second time to make him cry?"

The guy says: " The first time I told him I was bigger than him. The second time, I showed him".
