Mark this
One of my maths teachers (Slow Joe) used a different coloured marker for writing on the whiteboard depending on context, something like:-
Black - question
Blue - working
Green - answer
Brown - theory/hypotheses
Red - proof

I once got to class early, no-one around, and decided to have a little fun. Yawn, you say, swapping the caps is hardly imaginative. But I didn't, no, I unscrewed the nibs and swapped the bases - the cap and nib were one colour but the ink in the reservoir was another.

Lesson starts, he picks up the black marker and starts writing - black at first, gradually getting lighter and ending up brown. Blue goes purple then red. And so does my maths teacher. He goes abolutely mucking fental.

I eventually had to own up to avoid getting a friend in trouble but when I reported for punishment my housemaster was too busy trying not to cry with laughter to bother, Slow Joe being as popular in the staffroom as he was in the classroom.

We also once tried the watercress-on-the-carpet trick at Uni, but it didn't sprout it just rotted so when the guy got back after a weekend at his parents, his room smelt so bad even after the carpet was taken up and dumped that he was re-housed and his room was boarded up and never used again (the whole house was condemned anyway).

Presumably this QotW will be won by Rossi and Parfitt for revealing that they superglued the Titanic's rudder, removed the "No smoking" signs on the Hindenberg and cut the cables marked "Tsunami Early Warning System' during their recent tour of Indonesia.
