Looking for a game to play in class? Seek no more! 80% of college is super fun, but then there's that boring 20% that's, um, the reason you and parents will be debt until you're 45. You know what I'm talking about: Class! One brilliant Redditor came up with a wonderful boredom buster for that dreadful 9 AM lecture: Bingo! Print it out or keep it on your phone to play along the next time your prof is yammering on about blah blah blah, blah blah blah blah. See how many classes it takes until you land five in a row.
