19. The '8' game on calculator in mathematics
This is a 'brilliant' creation I invented when maths was a complete an utter fatigue. I was watching the clock hands slowly twist around the edges, picking my nails, marking the work I'd completed so far in red ink at the back of the textbook (glancing at the answers on the way), when I needed a new tactic. So, I came up with a game. Here's how it goes:
-Your right thumb is on the DEL button, and your left thumb is on the 8.
-Press down on both at the same time non-stop ferociously.
-End when either a line of 8s are across the screen, or there are none left.
Basically its a competition between your hands as individuals (I like making them argue with each other afterwards). After years of wasting time during maths classes, this is the outcome.
