These are the brain specimen drink coasters available from ThinkGeek ($20 for set of 10). Each coaster looks like a different cross section cut from a brain, and stacked resemble a whole brain. Me? I only operate with a quarter of a brain. "You're being generous." I probably am, it's definitely not the part of the brain that's good with fractions. *peeing pants* Or self control.
Keep going for a couple more shots. Then come over and let's make cocktails.
Thanks to Jeffrey, who's still pissed I left a beer on his coffee table without a coaster and made a water ring. That's your bad bro, you're a bad host.
