thank you !

[Scene: Ross's Apartment, the guys are there assembling furniture.]

Ross: (squatting and reading the instructions) I'm supposed to attach a brackety thing to the side things, using a bunch of these little worm guys. I have no brackety thing, I see no whim guys whatsoever and- I cannot feel my legs.

I presume 'worm guys' means screws and he has been crouching for so long that he has lost feeling in his legs. ;-)

I think:

worm : screw

brackety : bracket

whim: idea
