Four union members were discussing how smart their dogs were.
The first was a member of the Vehicle Builders' Union who said his dog could do math calculations, His dog was named "Tee-Square" and he told him to go to the blackboard and draw a square; a circle and a triangle, which the dog did with consummate ease.
The Amalgamated Metal Workers' Union member said he thought his dog was much better. His dog named "Slide Rule" was told to fetch a dozen biscuits and divide them into four piles, which Slide Rule did without problems.
The Liquor Trades' member admitted that both were quite good but he felt that his dog could outperform them. His dog was named "Measure" and was told to go and get a stubby of beer and pour seven ounces into a ten ounce glass. The dog did this without a flaw.
They turned to the Waterside Workers' union member and said, "What can your mong do?"
The Waterside Worker called his dog, which was named "Tea Break" and said to him, "Show these bastards what you can do, mate."
"Tea Break" went over and ate the biscuits, drank the beer, p*ssed on the blackboard, scr*wed the other three dogs, claimed he injured his back and filed a Workers Compensation form then shot through on sick leave.
