A whiffy stilton with Budweiser, stuff bunjies.
At school on my report in the Lower 6th, for Physics - "If he could learn not to sh!te himself (or herself as this is AB) at anything vaguely resembling a mathematical expression, he(or she) would be the greatest gainer". In the event I got an A1 and school creep prize.
Not a tank, but a double-decker bus. I was 14, school were not impressed and I got detention. I argued that it was careless to leave a bus lying around but lost.
