An Englishman, Welshman and a Pakistani man (stay with me on this) are in the Maternity Ward waiting room. Nurse comes through and says that there's been a problem, and the babies have got mixed up. She asks them to go through and see if they can sort it out.
The Englishman goes in first and returns with what is obviously, even to the most politically correct non-stereotyping eye, the Pakistani baby.
The Pakistani man protests, naturally, but the Englishman says "Look mate, one of those kids in there is Welsh - and I'm not taking any chances".
Every time I see an apostrophe used to form a plural, a puppy dies.
