I don't know about you, but I'd take Uhuru's nail clippings, Spock's nose hair, Bones' gall stones, Chekov's molars, and Scotty's ear wax before I'd buy Kirk's kidney stone. And don't get me started about owning any part of Sulu. Yuck.
This seals it. Some people will buy anything. Now, if only I could figure out how to turn that to my advantage. But somehow I get the feeling I'd be breaking a commandment. So I'll hush up.
