Cabbage...

Wombat was scrounging for food - as he usually did - when he remembered the only joke he could remember...
A man was walking along the road with a long leash in his hand. At the other end of the leash, tied on securely, was a cabbage. The man walked along, humming quietly to himself, oblivious to the stares he was attracting. Finally another man came up to him and said .."er.. excuse me... why are you taking a cabbage for a walk?" The man looked at his leash, saw the cabbage and slapped himself on the forehead. "Cabbage!!! The guy at the pet store told me it was a Collie!!!!!... (cauliflower)
Aaahhhhhhh hahahahahaha!! Wombat cracks himself up. Then he remembered, no one usually thinks that joke is funny. Funny about that! Oh well..
