Here are the ones I've read and thought were particularly entertaining:
An absolutely WONDERFUL Arrested Development fic bysloganeer
A funny Office fic where Dwight organizes the office and Jim calls Pam and makes a bet by angryhaiku
Oh, say someone wrote a gen Scrubs fic. :)
Keep your eyes posted on the Masterlist - the deadline for posting is tomorrow, and there should be 40ish fics in total. (There are... 5 in right now? 6?)
And guys, if you read someone's fic and liked it, it takes TWO SECONDS* to type "Hahahaha" or "Funny" or "I liked this!" Feedback is nice.
* may actually take you ten seconds or more, depending on individual typing speed.
(Tonight's new Office! And last night's 30Rock made me love Alec Baldwin even MORE. I just wish Tina Fey was better at hitting comedy highs. She's a writer, not a performer. But the show is still funny.)
