Animal talking!

A man walks into a pub and sees a horse at the bar drinking beer. Seeing this, the man turns to the bartender and asked: ‘What is that horse doing here?’
The bartender answers: ‘The horse is here for a bet. If you can make it either laugh or cry, you win the bet and get your drinks for free tonight.’
Then the man said: ‘Alright, but may I take the horse outside first?’
The bartender agrees. The man and the horse go out and after a few minutes they come back. When the come in, the horse is laughing out loud, so the man gets his free drinks.

The next day the man returns, asking if he may take the bet again.
The bartender answers he agrees, but only if this time he can make the horse cry.
Again the man takes the horse outside. When they return the horse is crying rivers of tears. Having seen this, the bartender offers the man his free beers and said: 'This is extraordinary! Please tell me now how you did it!’

‘Okay’, said the man, I’ll tell you: First I took the horse outside and said: ‘My willy is bigger than yours’ This made him laugh out loud, and the second time I just showed him.
