I laughed. I pretty much knew that, once Kahn was revealed as the villain, someone was going to yell KAHN!!! at some point. This movie was, in large part, a nostalgia piece, riffing on stuff we remember from the original series (miniskirts, Kirk banging alien chicks, Spock being logical, etc), but with not a lot of sense to it at times. It was ridiculous and unrealistic, but I admit I laughed out loud at the reference.
