I've pretty much done all, with a few exceptions.
get ears pierced - got two holes in each ear
do laundry at parent's house - all the time in college
crash on someone's futon instead of getting a hotel- someone always lets me sleep in their bed with them. either way, I'm crashing and avoiding the hotel part
put off going to the doctor - always. This reminds me, I still have to get my results when I got tested back in January.
drink shots with strangers - in Vegas
leave an annoying 2-person message on answering machine - just a couple of months ago, I wasn't planning on receiving any important/formal calls
help someone move out of a 6-foot walk up in exchange for pizza and beer - It wasn't a six-foot walk up. It was on the 4th floor w/ an elevator, but we did carry/drag some furniture and a bunch of luggage and a book case from Park Slope, down into the subway, got off at atlantic/pacific stop, up those stairs, and into a new apartment in fort greene. Now this has to count. And she bought me Uncle Louie G ice cream.
dye hair a funny color - never had the urge to color it blue or green or anything, but maybe one day, just to cross this off the list
EDIT: Great point by Ella Everywhere, I've had really harsh blonde streaks that did not suit me at all.
go to a rave - yup
pull an all-nighter - yup, to attend the above, and a couple in college
beer bong - I don't like beer
lazer tag - of course
10 out of 12, not bad.
Edit: 11 out of 12!
How many have you completed?
