An engineer and a mathematician went out for a drink. On the other side of the room, they spotted a gorgeous woman.

"I wish I could work up the courage to talk to her," said the shy mathematician.

"No problem," said the engineer. "Just walk halfway over to her, take a sip of beer, then walk halfway again, and do that over and over until you're next to her.

"But then I'll NEVER get there," said the mathematician.
