'Bumper Chairs'

Stumbled across a sign in the College ICT centre today. It said:

“For your own safety, please do not play ‘Bumper Chairs’, you MAY GET HURT”

I’m assuming that this game involves rolling the chairs into each other whilst straddled to your chair like an ICT gladiator. I like the fact that they decided to say you ‘may get hurt’ instead of you ‘will get hurt’. They’re essentially saying if you think you’ve got what it takes to play this game and survive by all means show us how it’s done, but if you don’t understand the complicated code of the ‘Bumper Chair’ athlete then graciously leave it to the experts.
