First you'll need to procure yourself a film that is heavy on beaver content. We recommend bypassing an internet search and renting The Beaver starring Mel Gibson. Gather friends and liquor of choice and when you deeply suspect that the appearance of a beaver is imminent, yell BEAVER! If you're right, everyone else drinks. If you're wrong, you drink, but at least you got to yell beaver.
