So two Irishmen are traveling to Australia.
Before they leave home, one of their 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.

Three guys, one Irish, one English, and one Scottish, are out walking along the beach together one day.
They come across a lantern, and a Genie pops out of it.
“I will give you each one wish, that’s three wishes in total,” says the Genie.
The Scottish guy says, “I am a fisherman, my Dad’s a fisherman, his Dad was a fisherman, and my son will be one too. I want all the oceans full of fish for all eternity.”
So, with a blink of the Genie’s eye, “poof,” the oceans were teeming with fish.
The Englishman was amazed, so he said, “I want a wall around England, protecting her, so that no one will get in for all eternity.”
Again, with a blink of the Genie’s eye, “poof,” there was a huge wall around England.
The Irishman asks, “I’m very curious. Please tell me more about this wall.”
The Genie explains, “Well, it’s about 150 feet high, 50 feet thick, protecting England so that nothing can get in or out.”
The Irishman says, “Please fill it up with water.”
