Carol - if you're from Texas, did you know that the woman who invented White-out was from Texas? She was a legal secretary whose hobby was painting. She brought her white tempera paint and a paint brush to work to correct her errors. Soon all the other typists wanted to use her correcting fluid. She patented the stuff, made millions, and lived happily ever after. Her son became one of the Monkees.
