My friend Waitman made a custom bumper sticker for someone he doesn’t know personally, but is apparently relatively famous: Theodore Gray.
Theodore is the co-founder of Wolfram, Inc. and the initial developer of the software program Mathematica from two decades ago. Waitman thought about it for three days before he ordered and sent it to him. Then he got worried about offending a guy that he didn’t know and wondered about his sense of humour.
Theo seems to have a sense of humour though because he replied:
“…I also collect cigarette lighters (don’t ask my why) and one of my favorites says “I’m famous on the internet”. What made someone think of putting this on the side of a lighter I do not know.”
