The next morning…
There was a loud knocking at the castle door. Snape, who had just been to the kitchens to see Stewey, Dewey, and Ratatalouie the house elves to give them some industrial strength detergent to ‘clean’ Winky, answered the door. Standing outside was a door to door salesman, wearing a crisp blue suit and a big name badge that said “Hi, my name is Eric – I like Monkeys”.
“What do you want?” said Snape , who was clad only in boxers and a feather boa.
“Umm, are you interested in purchasing a velvet cage of miniature monkeys?” Eric said hopefully, trying not to laugh at Snape’s pasty skin.
“No” said Snape as he slammed the door and went back to bed, his breakfast in hand.

THE END

The dare was as follows:
TabbyCat's dare:
)Must be centered around Professor McGonagall. I dont think she gets enough credit and therefore this dare must be about her.
2) Someone must tell a story that begins with "This one time, I was playing snog the hippogrif..." and end with "...and then the pineapple fell in the tiolet."
3) The gruesome twosome(Fred&George) must become sick due to something extremely weird. And when I say weird I mean extravaganty and insanely weird.
4) Snape must make multiple obvious costume changes through out the fic. One must include a frether boa.
5)The following items must appear:
-a tapdancing piece of toast
-3 house elves names Stewey, Dewey, and Ratatalouie
-A door-to-door salesman selling something
-a single lonely shoe
6) McGonagall must say "Potter! Put those green slimy suspenders back where you found them this instant!!"
