Try to play against opponents who are not as in touch with pop culture as
you are it will surely give you an edge.
If you're playing against friends and don't know a question, figure out
two options that are almost surely not correct, and casually mention that
you can't decide between one or the other. When one of your idiot friends
buzzes in with one of the wrong answers, you'll feel good about yourself.
If you get the first question wrong, why not restart the game? No one
likes to get off on the wrong foot.
