Karma?

Okay I admit it, we play the lottery a little. Nothing major, just once or twice a week. And Sheldon likes to get the scratch tickets, especially Lucky 7's, where you have to get three 7's in a row to win.

So the other day he's in the store getting a few grocery items, looks over at the scratch tickets and thinks to himself "should I get some Lucky 7's? Nah, later maybe."

So he turns to the casher for his total on groceries. She says "That'll be $7.77 sir.".
