Living at Marvin Minsky's house was a pretty strange thing, because he kept such interesting things there. And actually, after I lived there, I would go back and visit. And one time I just happened to be carrying a radiation detector with me, and as I walked down the stairs, the radiation detector went crazy. And so I was walking next to a closet, and I opened up the closet, and it was full of all these chemicals. And so I decided to figure out what was the radioactive chemical, so I would move a chemical over and walk and see which way the radiation was, and eventually I moved all of the chemicals out of the closet, but the radiation detector was still going off on the closet. I couldn't figure out what was going on. Then I noticed that the closet had kind of a secret compartment in the back of it, and I opened up the secret compartment, and there was a human skeleton. So I thought, wow. I'm not sure how I'm going to tell him about this. So I go up and Marvin and Gloria are up in the living room, and I say, 'I'm not sure how to say this, but there's literally a skeleton in your closet.' And they're like, 'What do you mean?' And I'm like, 'Oh, I found a secret compartment and there's a human skeleton behind it.' And Gloria says, 'Oh, that's where it got to! We've been looking for that for years.' And it was her medical skeleton from her medical school, and they'd hidden it back in this compartment. And I still didn't know what was radioactive, and I eventually found that there was a lens there that was something that Marvin had gotten surplus from an old spy camera or something like that they actually doped them with radioactive elements sometimes to increase the index of refraction. So it was dangerously radioactive, I got it out of the house.
