A Zoophile, A Pyromaniac, A Necrophile And A Masochist Are Siiting On A Bench...

... in a park. The zoophile comes up with a twisted idea: "Let's find a cat and fuck its brains out", he says. "Yeah, and then let's burn it to a crisp!", adds the pyro. "Brilliant idea, so we can fuck it, burn it, then fuck it again", says the necrophile. The masochist's eyes light up as he says: "MEOW!"

I'd like to dedicate this joke to our dearest David Cameron in the light of the recent piggate scandal.
