Satan's trampoline

Big and fat and bouncy,
Rectangle on the floor,
You bounce and bouncer,
'Till you can't take anymore,
You'll bounce for ever, you try and look so mean,
You'll wish you'd never been on Satan's Trampoline.
How he's gone and got you,
He's got you and got you,
He's got you where he wants,
Dressed in shorts and vest,
You look like a real ponce,
You'll bounce for ever, you try and look so mean,
You'll wish you'd never been on Satan's Trampoline.
How many times can you bounce up and down on Satan's big old Trampoline?
I do not know, but I'll let you have a go on Satan's big old trampoline.
