Singularity

I didn't start watching Doctor Who until a few years ago, and I can say I was familiar with the "reverse the polarity" cliche from Star Trek long before. I draw back to the pen-and-paper RPG, and also the TV Tropes entry: "In the episode "That Which Survives", Spock orders Scotty to reverse the polarity of a "magnetic probe". Scotty's incredulous, "reverse polarity?!" is not only Narmtastic, but qualifies as the Trope Namer."
