Scene: '93 or thereabouts, in a uni computer lab and I am bored. I log on remotely to an ONR Y-MP I have access to for research. Huge-ass machine in its day, but notoriously slow for single-CPU jobs. So I decide to compile xtetris on it, which was surprisingly simple (why did a Cray have X on it? who knows...). And then I export the display and start playing the slowest game of Tetris, probably ever. Punchline: I was sitting at the console of an SGI Reality Engine at the time, a machine not known for slow graphics... my lab-mates couldn't help but stare and ask "why on earth is xtetris slow on the SGI?", "oh, no that's just a Navy Cray" <grin>.
