The Helm Game
This lil game I've encountered isn't necessairly just for the workplace, it can be played just about anywhere where there's plenty of unsuspecting people (my personal preference is in train stations). This game is best played with 2 or more people, and if the place you are playing in is particularly crowded then the further away you are from each other the better. Now the objective of the game is to say 'helm' or 'helmet' in a very specific funny voice (sort of like trying to say the word while simulataneously taking in a sharp breath) starting out quiet (barely audible) and increasing steadily in volume each time, now there are 2 conditions (1 or the other) to winning or losing this game, either making someone outside the group burst out laughing (you win), or if someone outside the group tells you to shut up (you lose).

The inventor of this game is my best mate's younger brother, who played it with a mate of his during his year 9 SATS exam, the result being he and his accomplice were thrown out of said exam, but to his credit he and his mate did get pretty loud before they were busted by the invigilators and no doubt gave the other students some half-decent entertainment at the same time.

me and my friend
play a game called Penises and Vaginas.

Very very similar to this except that the rule is that if you think you've won in the loudness section - you then have to yell"vagina!" at the top of your voice. If they can yell "penis" louder - then you lose.

Lots of fun.

Yeah
I played this as just "Vaginas".

Where you just kept shouting vagina louder and louder until someone gave up or you were thrown out of the crematorium.

Titwank
We played it for years with the word 'titwank', sometimes with the word 'face' on the end for extra kudos
