First entry (I somehow managed to sign up for TWO fics, both of which I forgot about until yesterday, whoops!) is from the prompt: "Buffy goes to fat camp." I offer my submission in the form of haiku.
Buffy Goes To Fat Camp: Haiku
Season one thigh-highs
Accentuate doughy knees
Long pants hide cankles*
Pancakes - pizza - pop
Indian soap operas
Need to kill more vamps
Xander and Willow
Sneaking Summers' snacks at night
Joyce thinks, "Where's the food?"
Steadfast counselor
Searches through pillowcase
Chocolate treasure
Push-ups and pull-ups
The Slayer will not tire
Other campers plot
Lunch lady Doris
Bribes grease hands- she greases food
Buffy's ribs vanish
Cakes, pies and doughnuts
Not only booty at camp
Buffy's heinie spreads
Demons hear of this
Corpulent, lazy slayer
Time to take over
(Okay, I swear the second entry is actually good.) * cankles = calf-sized ankles
