A trope commonly found in animation; two or more characters, usually hiding from something, have found themselves in an entirely pitch-black environment. One of them remarks on or complains about how dark it is. The other strikes a match - but the sudden burst of light reveals that the characters are, in fact, standing in the middle of an amazingly dangerous environment, be it a room filled with monsters (who have, up until this point, been remarkably quiet) or - to give the danger an added boost of irony - a room packed with an unimaginably large store of explosives (especially if the "match" turns out to be a Dynamite Candle).
