Jools,
Have they decriminalized weed in Oz? Please advise when the shirts start to sell. Maybe I'll eat crow. I WOULD like to point out a grammatical problem in the joke. If the wife wants "twins,'" giving one does not fulfill the request. To be succinct, I believe it would have to say, ".. so I gave her two," then, maybe, an A7 and A10 sitting next to eachother.
