Horse walks into a bar and gets himself a pint.
A donkey is sitting beside him and says "you're a big lad, did you ever win anything?"
The horse turns round and says "yeah, I won the Derby on the flat and the Grand National over the jumps"
The donkey, thinking "Heck, how can I match that, that's impressive" So gets out his mobile phone and finds a picture of a zebra.
He shows it to the horse who responds "What the Hell is that?"
The donkey replies "That's me when I used to play for Juventus"
