Questions for the mighty flist

1) Ok, unadrift    and I have been debating this and the dictionary is no help. Is it: racking one's brains; wracking one's brains, or (::squints::) wrecking one's brains? How do I not know?!  ETA:  It's racking. Thanks sapote3  !

2) Also, into what position do I need to contort myself to get my left hip to click? It clicked out the other day, and now I have an irritating array of painful limitations, like not being able to lie on my back with my knees tented, or slouch on the sofa with my feet on the table in front of me. Or, I can slouch that way, but only if I don't mind sharp, grindy pain through the back of the joint when I get up again. I am not impressed. Fix me! ::pouts::

3) And, for reasons having nothing to do with any stories I am currently writing, particularly not anything that was supposed to be, like, 1000 words but might already be disturbingly longer... in a team!orgy, who would be the ultimate boss? I'm leaning towards Ronon, but, Teyla? Or does Rodney have secret sexual power over them all? Does John bring his dubious natural leadership into the bedroom?

4) Button then zipper, or zipper then button?
