Two Irishmen are traveling to Australia. Before they leave home, one of the dads gives them both a bit of advice. "You watch them Aussie cab drivers. They'll rob you blind. Don't you go paying them what they ask. You haggle."
At the Sydney airport, the Irishmen catch a cab to their hotel. When they reach their destination, the cabbie says, "That'll be twenty dollars, lads."
"Oh no you don't! My dad warned me about you. You'll only be getting fifteen dollars from me," says one of the men.
"And you'll only be getting fifteen from me too!" adds the other.
A heart surgeon came to a mechanic to repair his car. The mechanic had a look at the car's engine, opened a valve and fixed it.
The mechanic said, "I repaired the engine which is the heart of the car. You also operate on the hearts of humans, so our jobs are quite similar. So why it you earn more than me?"
The doctor replied, "Can you repair the car when the ignition is on? We can!"
Another man and I share a locker at work. Noticing that it needed a new combination lock, my partner said he would pick one up on his way to work the next day. It occurred to me later that I might not see him in the morning. How would I find out the combination?
I needn't have worried.
When I arrived at work I found that he had used the locker before me and had left a note reading: "To find the first number subtract 142 from your high score the last time we went bowling. The second number is 16 less than that. To find the third number subtract 1.87 from the amount you owe me."
