Here is a funny English / Chinese translation:

Small Horse = Tai Ni Po Ni

A horse goes into a bar and sits the bar tender comes over and asks why the long face pal.

"Some horses are so polite that when they come to a fence, they stop and let you go first." 

 One day the thunder god was out riding his favourite mare, and he bellowed out at the top of his lungs "I'm Thor",
and the mare replied "You should be, cause you forgot the thaddle thilly".
