I donated blood today, and if you live in Austin (or anywhere really) you should too, as they are mega-low on the blood donations this summer [unless of course you are scared to death of needles like Dr. M]. Not only will you have the fun of answering a series of semi-embarrassing questions (they aren't so bad, although I don't often get asked if I've ever accepted money for sex or had sex with an African), but you will also get tasty Nutter-butters, or the cookie or snack of your choice afterward.
Or you could just purchase this blood drop mascot costume for $1200 and wear it around. Doesn't that seem like a lot for a costume? I guess mascot costumes must be more heavy duty than your usual Halloween/costume ball fair.
