A Melbournite and a Sydneysider were arguing about which city had the best beer. The couldn't agree, naturally, so the Sydneysider said "I have a mate who's an analytical chemist, why don't we send him a sample of Melbourne beer, and a sample of Sydney beer, and let him decide." The Melbournite agreed, so they put some Melbourne beer and some Sydney in two, unmarked containers, and sent them to the lab. A week later the Sydneysider rang the lab. "Did you get those two samples I sent you" "Yes" "Well, what did you find" The lab tech replied; "Well, mate, I'm sorry to tell you this, but both your horses have jaundice!"
