A man walks into a bar?

and the bartender says, "hey i bet you 100 dollars you can't make that horse in the back laugh."

So the man goes into the back and comes out a couple seconds later and the horse is bawling with laughter. The bartender asks the man how he did it but the man says, "It's a secret."

The man comes back the next day and the bartender says, "hey if you can make that some horse cry i'll give you 1000 dollars." So the man goes into the back and comes out a couple seconds later and the horse is crying profusely. The bartender asks, "How did you do that?"

The man replies, "First I told him I had a bigger dick than him and the second time I proved it."
