A Scouser, a Manc and a Rasta are all in the maternity ward waiting for their partners to give birth. The midwife comes out and tells them congratulations, they're all fathers of beautiful healthy boys, however unfortunately they've run out of the name tags, and the babies have been mixed up, so if they could each go in and identify their sons from any family resemblance etc.
The Manc wants to go first, so in he goes and comes out with a black baby.
The Rasta looks a bit confused, "Excuse me", he said, "but don't you think he's likely to be mine?"
"Probably", said the Manc, "but one of them in there's a scouser, and I'm takin' no chances !!!!!"
