I like all the Ethan Rayne episodes (probably spelled his name wrong), but this one was a hoot and a half.
Once I'd finished watching it the first time, I had to rewind the tape back to the part where Giles-demon jumps out of the car and runs after Maggie especially following his line of (paraphrasing) "I refuse to act like a monster just because I look like one."
Cheers,
