I've known a few master level BS artist, and am amazed that most have never gotten themselves into a sales position. If they could only use that power to sell good merch instead of their own non-existant or crappy skills, they'd be rich.
For instance, we had a guy here who was at the Grandmaster level at BS. He was very, very good at talking himself and his skills up, and never delivered. For instance, if you asked him to cut a couple of boards to length, he'd talk for hours about how great he was at cutting boards, about all the boards he cut in the past, and about how he could modify the saw to be better when it came to cutting lumber. He would then take the saw apart, destroying it in the process, and disappear for a few days having never cut a single board. He also borrowed a truck from another organization, and basically destroyed it. He promised that he'd totally rebuild the thing, took it half apart, then left.
