somebody mentioned 'cwm' in a post today, which reminded me of some of my favorite words:

CWM/CWMS
BRRR
PFFT
PSST
TSK/TSKS/TSKTSK/TSKTSKS
CRWTH/CRWTHS <--my personal favorite.

they're all legal scrabble words, even if they do raise some eyebrows.

(btw, anyone else out there love scrabble? there's a great online version called wordox... but it's quite addicting. i'm a recovering wordoxaholic and haven't played in ages for fear of a relapse)
