Geordie bloke walks into a pub, says to the barman:
"Pint Of Whitbread Please."
Barman pours him a Pint and the Geordie takes his seat. Five minutes or so pass and the Geordie has to answer the call of nature. He puts his pint on the bar and says to the barman:
"I'm jus gannin for a piss, mate, make sure ne one touches me pint!"
Geordie goes to the gents, 2 mins later he opens the door to the bar to find a tall Black woman, jumping up on to a stall to fart into his pint!
Geordie runs over to her and says "Hey, you Fart in me Whitbread!???"
Woman replies " No I'm Tessa Sanderson!"
