For some reason, this sublimely stupid episode is one of my favorites in the three seasons of Slayers. Through some masterful misreading of an old tome the girls get suckered into dressing up like this and singing a song (which Zel has to sing through first, as he's the only one who can read the language at all). Even better, the costumes can't decide whether they're from Sailor Moon, Nurse Angel, or half a dozen other possibilites. It's just plain fun.
