The bartender asks, "What can I get you?"
The first Canadian turns to the other and says "You first."
The second Canadian shakes his head and replies "No no, you go ahead eh?"
The first smiles and turns to the bartender, "Get my friend here a shot of your best Canadian whiskey!"
As the bartender is pouring, he turns to the second and asks "And for you?"
"What do you mean?" he asks, "You're pouring my shot right now eh?"
"Oh right" says the bartender and turns back to the first, "Anything for yourself?"
"I'll have what he's having!"
The bartender pours another shot and says, "Hey, isn't there supposed to be a punch line in here somewhere?"
The two Canadians look at each other, then back at the bartender, and one of them says, "What are you talkin' aboot?"
