Crack recs?

[amberfocus]

Anyone got some good Doctor/Rose (any version of the man) crack fics they can rec for me?  I'm in pain and I need cheering up and I'm sorely in need of a good laugh.

ETA:  Actually Donna and Jackie and Jack (Who, not Torchwood) crack fics are okay, too.  I just tend to lean towards Doctor/Rose.

EATA:  Wouldn't say no to anyone writing me some crack, either...
