You'll like this one then...... (not so short though)
Two dogs in the Vets, one is a mongrel the other a pedigree Alsatian.
Alsatian : Looks over to the mongrel and says, what the hell you crying for bro?
Mongrel : I'm having my bollox chopped off!!
Alsatian : Daaawwwg, that's bad, why such drastic measures?
Mongrel : I was just snooping around the front garden of my owners place, when the cat next door sniffed under the hedge and came through a small hole into my garden. The cat then proceeded to sniff round my garden, at which point it's tail lifted up high and exposed, well, you know
Alsatian : Yeah go on.....
Mongrel : It's been a while, so I just gave the cat a Rocket Ronnie up the ar$e!!
Alsatian : And you're in here to have your bollocks chopped, that's a bit extreme.
Mongrel : My owner was informed of my actions by the cat's owner and as punishment I'm in here about to suffer the worst day of my life! So what you in here for then? You don't look upset to be in the Vets?
Alsatian : Well, I've been sent by my owner as a result of actions in our mansion the other night?
Mongrel : Do tell......
Alsatian : My owner was just getting out the shower, she's tall, blonde with a great body. As she left the bathroom her white towel slipped from around her body and dropped to the floor. As she bent over.....
Mongrel : yeah, go on......!!
Alsatian : She bent over to pick up her towel and her hot steamy body was glowing, and let me tell you, it's been a while. So I just did it!! BANG!!!
Mongrel : You're having a laugh!!
Alsatian :
Mongrel : Hold on a mo..... I've shagged the neighbours cat and I'm loosing my gonads! You on the other hand are happy as Larry, so what are you at the Vets for?
Alsatian : I'm here to have my nails clipped!!!!!!!!!
