fic search!

okay, i've been rereading some old stuff, and remembering random bits of stories but not where they came from.

i remember reading one where buffy deliberately ordered pizza heavy with garlic and then breathed in spike's face, which caused him to break out and basically have an allergic reaction, which pissed xander off.

i feel like i should KNOW what this was from, but i'm coming up blank. any ideas?

thanks!~
