A game to be played to enliven fucking boring school trips to Sellafield. When speaking to the Sellafield staff who show you around, subtly insert the word 'orifice' into as many questions as possible.
'So, where are all the orifice workers here?'
You will quickly discover that it is actually quite difficult to shoehorn many orifices into casual conversation. When you discover this, you can take the 'Dan Wakefield Option' of simply handing back your visitors badge at the end of the trip with the words 'Thanks, orifice'.
