The only dinosaur still in existence. Known only as a fossil until very recently when a male specimen turned up in an art gallery trying to get off with an overweight Down's Syndrome man. Plans to keep the creature in captivity have been shelved as it has such a vile odour.
Who's the hideous man trying to get off with the fat spacker?

That's not a man. That's a Briggsysaurus.
