Next time you’re watching Bear Grylls take on mother nature, grab some brews and invite your friends over, because you’re in for a wonderful hour-long drinking game.

The rules are simple. You have to drink any time one of 4 things happens:

1) He says anything is “deadly,” “lethal,” “fatal,” or anything of the sort. You’d be amazed how often he stresses the possibility of impending doom.
2) He spouts off a fact or anecdote of dubious origin. How many times in each episode does he say: “last year, two campers came here for a weekend and died of thirst in 6 hours. Their bodies were found a week later as skeletons being eaten by maggots with 2-inch fangs.” Any time he tells one of these urban legend-like “factual” stories, it’s drinky time.
3) He eats something disgusting. Admit it: you pretty much watch the show and count the seconds until he bites the head off of some poor, revolting live animal. There’s no shame in owning up to it. This works for drinking nasty shit, too. The good thing about this rule is that Bear can rarely wait more than 30 minutes before a murderous food craving kicks in.
4) He takes an article of clothing off. Bear seems to like getting naked whenever possible. If he strips down completely to his birthday suit, you should probably chug an entire brew.

Another fun way to play is to assign different people to drink for each rule, although I prefer to just get everyone to do it for all of ‘em.

Now turn the TV on to the Discovery Channel and hit up that Man Vs. Wild marathon… It’s gonna be a long night.
