When you win some crappy prize at an obscure raffle/event from buying $20 in tickets that you could just go out and buy at a store for a couple bucks.
A: "Look at this cool bunch of flashy yo-yo's I won at my church's fundraiser last night, guys! Look! They spin and stuff!"

B: "I see you've finally won the Grape Lottery. Congratulations."
