My wife's suggestion was to start a "Pool Night", so I did. I've provided links to Word docs which contain the details. I invited four others (so 5 players total), and we play the first Friday night of the month. 3 nights (or "sessions") make up a "season", and the winner of the Season (best record) gets to pick which game they want to play in the next Season. (I'm working on a better prize for that, but that's the current model.)
Each player comes with 20 bucks. The house (that's me) takes $50 for food and beer, and the Session winner takes $40, and the runner-up takes $10.
We ended up taking this summer off due to scheduling issues. I'm trying to start it up again, but this time with only four of us.
Attached are all the details, including our records, house rules, head-to-head stats, etc.
While 12 sounds like a fun party, it seems like you'll have a lot of guys getting frustrated when two lesser players take the table and are banging around and not able to pocket in a timely fashion. I think 4 or 5 is ideal. I actually think 6 may be too many. Then again, none of us are all that good!! If your 12 friends play jam-up, it may work.
OTOH, if you have 12 friends who are into it, perhaps you can break them into groups and have 2 or 3 different pool nights. More pool for you!

Spring '08 Season Results (note: my original approach was to make the order of players switch around by assigning P1, P2, P3, P4, P5 to the player in order of their record from the prior session. The best player was P1, then P2 and so on. The idea was to have the night culminate with the supposed two best players from the prior session (P1 and P2). For next Season, I decided to just have the match-ups based on first names, and forget about the culmination thing -- keeping track of which player was which was too confusing):
