halloween costume ideas & absenteeism

yep, been mia for a while now, at least here on my own blog. sorry for the lapse, but there's even more of nothing to write about lately. life is pretty dull, only thing that's been going on is the monotonous day-to-day of work & then nothing of interest when i get home.
we are going to vegas in about 4 weeks so any suggestions or ideas for must-see, must-do, must-eat are welcome.
also, s & i are invited to a halloween/housewarming party on the 30th, so trying to come up with some costume ideas. i wouldn't even bother, but the invite reads "Halloween costumes strongly recommended; if you do not wear one, one will be provided for you." which frightens me. here are some of the ideas i've been tossing around:

salt & pepper
jack & jill
plug & socket
mac 'n cheese
pumpkin pi
a salt & battery
hansel & gretel
pair of dice
hurry up & wait
almond joy & mounds
upper & lower gi
lady & the tramp
burger king & dairy queen
spoon & fork
sick & tired
war & peace
peace & quiet
princess & the pea
nuts & bolts

(if you need to inquire as to what any of these actually involve, just ask.)
lunch break is almost over & i'm working 8 to 6 today because i'm leaving early for some errands on wednesday & we're now required to work late one night a week because apparently no one returns calls to schedule appointments between the hours of 8-to-5 despite numerous messages. they're hoping we'll catch people at home from 5 to 6 and get them scheduled. ha! didn't work the last two times we tried it, but hey, they're all about beating a dead horse.
