See, to see a twat you have to be a twat. To pull off a prank you need to be a cockspank (at some time in your life). And if there's one thing worse than being the butt of a joke it's being just a butt. A big fat horse's arse.
As George W Bush famously said "There's an old saying in Tennessee - I know it's in Texas, probably in Tennessee - that says, fool me once, shame on - shame on you. Fool me - you can't get fooled again." (go on, click the link - it's solid gold!)
Everybody, young and old, shallow or profound, lowly or high and mighty can get in on the act. Drop your guard and go with the flow, Joe. Call it therapy
So, don't get upset off if you got caught out - don't get mad, get even... and you've got all year to plan your revenge!
