That was AMAZING! Wall head-butting. Haha! Wow...
Some other good drinking games are drink while you think (basically, you have to name celebrities (most common category choice). Example: 1 - Angelina Jolie. 2 - James Hetfield. The follow on answer's first name must have the same starting letter as the previous answer's surname (Jolie - James). Doubling up (Jenna Jameson) swaps the order of progression round the table. While thinking of a retort, you must continually drink until you put forward an answer/suggestion. Harder than it sounds. You get pissed QUICKLY.
Movie quote game is good too. Someone quotes a line from a film and you continually drink until you name the movie the quote came from. If you simply cannot successfully name the film, you take a two finger width measure worth of a drink.
