The whole climbing-on-tetras --> climbing-on-robots thing seems a little shaky to me, so I feel justified in making my own shaky connection:
At the end of this year's kickoff, Dean and his buddies were in a pool (at this point the good people of CD, who are desperate for a water game-- even though it would be entirely too far beyond the scale of a high school robotics competition-- collectively peed their pants, immediately started to devise an idea for a floating robot, and overlooked the joke completely

). But what if "pool" was interpreted differently? Then the robots, far from swimming around an arena and frying their electronics, could be playing billiards (noun: the game of pool), could be placing poker-chip-like game pieces into a pot (noun: a common pool of money) in the middle of the playing field, or could be forming teams and alliances (verb: to pool together) dynamically throughout the game.
On second thought, that doesn't sound shaky at all.
