Dean teaches Castiel the "That's what she said." phrase. Hilarity ensues.

thanks that was awesome

You're welcome. Now, every time I hear the phrase, all I think of is a totally oblivious Castiel.

Hilarious wincest crack fic classic...
Dean in drag during a pride march.

kellifer_fic's doll!Dean series (http://kellifer-fic.livejournal.com/tag/doll!dean) (Gen; PG; ~5,500 words)
Dean is a doll. Literally.

But It's Five! (http://bellatemple.livejournal.com/428474.html) (Gen; G; 429 words) by bellatemple
Coda to 5x10. Five things the Colt can't kill

Walk Like A Man (http://hkath.livejournal.com/506072.html) (Gen; PG; ~5,000 words) by hkath
Dean gets his ass cursed at a truck stop, and it all kind of snowballs from there: the virgins, the breading, the space ninjas.

Some Wishes Are Worth Waiting For (http://runedgirl.livejournal.com/45289.html) (Sam/Dean; NC-17; ~6,400 words) by runedgirl
for the prompt: Sam and Dean deal with a spirit terrorizing a family just before Christmas, and the family invite them to spend Christmas with them. How do they deal with a full on Christmas with all the trimmings?

How Many Floors to Realize (http://lazy-daze.livejournal.com/606727.html) (Smith/Wesson; NC-17; ~26,700 words) by lazy_daze
AU from the end of It's A Terrible Life, in which Zachariah decides to keep stringing them along a little while longer, because damn if they aren't somewhat entertaining, right?

I repeat, we have normality (http://irnan.livejournal.com/76830.html?view=1376798#t1376798): Teen-chesters with tooth aching Dean and Sam who just read "Hitchhikers Guide through the Galaxy". Lovely and funny

California Dreaming. (http://rivers-bend.livejournal.com/371853.html) John leaves Dean to pay rent with a hammer and a paint brush one spring. I don't know why, this gives me a warm, fuzzy feeling.

When you think he's half asleep (http://teand.livejournal.com/173362.html?view=2695474#t2695474). Dean is an awesome cat.

Is J2 ok too? I always feel better after "Your brains are no match for my tractor-beam". (http://longsufferingly.livejournal.com/10691.html)

Chemical Warfare (http://northatlantic.livejournal.com/578636.html.) Dean blows up the chemistry lab in school.

Knock before entering (http://ciaan.livejournal.com/341398.html). One of the things that annoy Sam is that Dean has no sense of privacy.

The ravages of war. (http://unhobbityhobbit.livejournal.com/271457.html) One word: prank-war!

Peanuts. (http://lassiterfics.livejournal.com/133201.html?view=2610513#t2610513) If you're getting your gossip from God, it's kind of awkward. Chuck POV - and SO good!

E-mails. (http://www.fanfiction.net/s/5758874/1/Emails#) So good for a bad day....

The pen is mouthier than the sword. (http://kellifer-fic.livejournal.com/190554.html) Dean always has to do things the hard way.

Haiku (God bless you) (http://superbadgirl.livejournal.com/765370.html) One of the funniest things I've read.

I could name more, but those will get you out of the funk. Have fun.
(Oh, all are gen, except of course the J2-fic)
