Pub Drinking Games

It's my 21st birthday night tomorrow night, and we organize fun & frolic all night, do you have anything that can add?

For all the games we have today is a balloon modeling challenge and a team game to say euphemisms. Both teams get a min to write as many euphemisms for the word "penis" ...

We have inflatable guitars as prizes, and do not mind forking out for a few drinks, but not much!

All parties must be played in a pub in central London during a night of Sat

Ideas?

Some American football Super Bowl Drinking Games, but most can be adapted to almost anywhere,

In beer pong, you'll need a table tennis table or even a pool table covered and plastic cups and ping pong.

Jacks with a deck of cards is always welcomed! Taking first reviewed the names receiving a drink, the second, he bought the third goes to the bar for him and the fourth drink, he must buy one or all players with the same thing! Warning never too early or you do not last very long. Cheers!
