Pete was telling Lionel about his company's latest product. Pete said, "It's super-thin body armor. It sprays on. Or you can bathe in it. Just pour a small bottle of it into a bathtub of water. It's like a second skin, but you can't see it or feel it. It doesn't block your pores from breathing. But it does block most bullets and knives from penetrating your skin. You'll feel the bullet or knife strike you, but it won't hurt. More important, it won't kill you." Lionel said, "Wow! That sounds like a killer product. Every soldier, cop, and paintballer is going to want it. Probably most criminals too. When's it going on sale?" Pete said they weren't quite ready. They still had to solve one big problem. "What's that?" Lionel asked. Pete said, "We don't know how to remove the armor." Lionel said, "Why bother? Who would want to?"
