My favorite trope ever: The whole team is exposed to a virus: The Dreaded Gay Virus! Everybody panics and angsts at their new sexuality...and then succumbs to their urges. Then it is revealed that "oh wait, we made a mistake," it was a completely harmless virus, not The Dreaded Gay Virus. Awkwardness ensues. (This isn't as far-fetched as it might sound: for a while there the US military was trying to develop a kind of chemical warfare that would do exactly this. I'm not kidding. Search Gay Bomb on Google.)
