Hints:

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
