A bloke goes into a bar with his dog on a lead. The barman asks "What kind of dog is that?"
"It's a long nosed, short legged, long tailed terrier" came the reply.
"Never heard of it" says the barman, "I've got a Doberman that would kill it it seconds"
"Twenty qiud say it couldn't" came the reply
"Your'e on" says the barman.
They take to two dogs into the back yard and let them loose. Within 30 seconds the Doberman is left dead in a pool of blood.
"Tell me again what your dog is" says the distarught barman as he hands over his £20.
"It's a long nosed, short legged, long tailed terrier" replied the owner, "though some people call them crocodiles!!"
