TGIF

A man is out for a stroll one evening when he comes across a magic lamp. He rubs it, and out comes a bone-thin genie with a face full of wrinkles.
"Wow!" says the man. "You're a genie! And I found your lamp! That means I get three wishes!"
"No, no, no", the genie said. "I am a very old and very tired genie. I only have enough energy to grant one wish."
"Oh, um, ok then", said the man. He had to think carefully about what he needed. He thought about how he detested travel. "Wait! I've got it! I wish I had my own personal highway that took me wherever I wanted to go!"
"No, no, no", the genie said again. "That wish is too big. I am too old and too tired to grant such a big wish. Ask something smaller."
"I see", said the man. He thought about what else would be useful. "I wish I had the ability to understand women!" The genie's eyes widen, and he turns to the man.
"Two lanes or four?"
