Drinking games

I don't drink alcohol much, so I've never been one for drinking games. It's just not the same with ginger beer.
I make an exception for movie drinking games, because they're often more fun when you're not drinking alcohol, as then you get to watch the whole movie (the rules then are how long you can go before needing to run to the toilet). The trick is to look for various peculiarities in the movie, and drink each time you see one (usually double drinks if you miss it, in our house rules).
I've played it often with Star Wars (the original series) - there's a very common set of rules existing on many sites (e.g. here).
Watching Lord of the Rings: Fellowship of the Ring (now there's a movie that's still a mouthful initialised LOTR:FOTR - bleh) the other night, it occurred to me that it was also a movie, or series of movies, that could do with a similar game. So I looked it up, and found that, of course, many people had already had a similar idea. I particularly like this one, which is very funny, but not really practical. This one was also very funny, and a lot more practical, as was this one, but although categorised ones are good, because you can easily pick a subset of the rules and just play those when you feel like it, it does tend to mean you end up with a LOT of rules, so it's harder to play and keep track of all the rules (a major drawback in terms of our double-if-you-miss-one house rule, you end up drinking way too much too quickly). So I've made up my own set of rules, not too long, though I may add a few rules later. Thanks to those three sites mentioned for some ideas on rules.

Take a drink when:
- Bilbo's book is mentioned
- Someone drinks anything (2 if they belch afterwards)
- A Hobbit talks about food
- Someone sings a song
- Someone speaks a language other that English (dwarvish/elvish etc)
- Sam says "Mr Frodo"
- Frodo says "Oh, Sam"
- Black Riders appear (2 if they speak)
- The Great Eye appears
- Someone draws a sword, but doesn't attack anyone
- Pippin acts like an idiot (2 if it puts his friends in mortal danger)
- Frodo nearly gets killed
- A hobbit gets picked up and carried
- The one ring appears
- Someone tries to give the one ring away (2 if they succeed)
- Someone tries to snatch the one ring away
- Someone falls off a cliff/tower
- We see a close up of someone's unusually long or dirty fingernails
- Gollum hacks up a "gollum! gollum!"
- Peter Jackson makes a cameo
- Someone who was apparently dead turns up again/recovers

Well, let me know what you think, and I'll decide whether it's worth reviewing any further.
