A donkey meets a racehorse in a pub. They get talking, find each other to be good company, and after "last orders" the racehorse says "Why don't you come back to my stables, we've got all mod cons, I've got a fridge full of beers...."
So they go back to the racehorse's stable. The walls are decorated with photos.
"What's that?" says the donkey. "Oh, that's me the time I won the Grand National"
"What's that one?" "That's me with the Queen at Royal Ascot"
"That one?" "That's me at the Derby..."
The donkey's thinking "I can't compete with that - this racehorse is a superstar, I'm just a donkey from Blackpool beach". He drinks up his beer and goes home.
A couple of weeks later, they meet again. After "last orders", the donkey says "This time, we'll go back to my stables"
They arrive at the donkey's stable, and on the wall is a huge picture of a Zebra.
"What's that?" says the racehorse.
"Oh, that.... that's me when I played for Juventus..."(*)
