Rube Goldberg (left, 1883–1970) was famous for illustrating preposterous machines that performed ridiculously simple tasks.

While working in several “humiliating and low-paying jobs,” Scott Adams M.B.A. ’86 (right) created a comic strip during his off-hours starring Dilbert, a mash-up of his former coworkers.
