There was a guy I used to work with who, as far as we could tell, pretty much lived on Red Bull and coffee – he must have got through about 6 cans a day. He looked a bit like the Danny DeVito character The Penguin except considerably faster moving and very jerky, several tics and stammers which may or may not have been casued by the excessive caffeine consumption.
The only other thing about him was that he was constantly in the toilets. He became known as the Trap 4 – a joint reference to the 1980’s spoof horror claymation programme The Trapdoor, and his favourite toilet compartment, trap four in the row of cubicles. Everytime he came out of there, the cubicle looked like it had been on the recieving end of a particularly violent carpet bombing campaign.
