I love it when someone says something that is totally funny, but is so serious about it that he doesn't even realize what he said. This latest gem comes courtesy of my dad. We were driving along the highway when I spotted a sign for free cremation....
Me: Wow, free cremation! That's a great way to spare your family the expense of a burial. But thee billboard also said something about donating your body to science, so I guess the medical schools around here need cadavers for students and research, so they use your body for anatomy classes and cremate it afterwards.
Dad: Yes, that's right! They're so short of cadavers these days. When I was a med student, our class had 40 cadavers! That's just 4 students to a cadaver, which is pretty rare today.
Me: So what do med students do now?
Dad: Oh, many schools use plastic cadavers. They're really great. It's so much easier to identify veins and other parts of the anatomy with these plastic cadavers. They're so lifelike!
