Bob: “She got me a gym membership for my birthday.”
Doug: “That is such a Homer Gift. She is tired of being seen in public with your tubby ass!”

The star player in basketball game slipped during the last seconds of the game causing the ball to get accidently hurled at the net and making the winning shot and so "pulling a homer"
