Three Irish nuns die and arrive at the Pearly Gates.

St. Peter says, "I’m sorry. I don’t know what happened. But we’re full. Go and wait over there." He points to a hard marble bench. "I’ll sort things out. I’ll come back to you in a minute."

The nuns wait for one thousand, two thousand, three thousand years. Eventually, St. Peter comes back to them. 

"OK," he says. "All sorted. One quick question. Give me the correct answer and you’re in."

To the first nun, he says, "What’s the capital of France?"
She says, "Paris." 
He says, "OK, you’re in."

To the second nun, he says, "What’s the capital of Italy?"
She says, "Rome." 
He says, "Okay, you’re in."

The third nun is a Reverend Mother, all pumped up and in high dudgeon for being kept waiting. She says, "Now what’s all this keeping me waiting all this time? Here am I, I’ve given you the whole of my life. This is not what I expected. It’s not good enough. And to have to sit with the other nuns, as well. For three thousand years. It’s certainly not acceptable."

"OK," says St. Peter. "One quick question and you’re in. What’s the capital of Swaziland?"
