I once responded to an advert in the paper for an IQ test from 'MENSA'. I received the paper and arranged a quiet moment for myself, with myself.
The scene was set, poised with my pen, stopwatch and glass of water. This was to be an exact gauge of my mental ability.
I commenced, carefully considering every quesion on the paper and answering to the best of my ability.
I finally reached the end of the test wher it said PTO.
On the back page it said :-
'Please return paper unmarked, or completed with cheque for £8.95'
FUMSTARDS!
