He Has To Spin

Dr. Harold Weirdland usually ran out of blackboards before he came up with answers, but he bought an iPad and, lo and behold, he came up with answers.
“We age because the world spins!” shouted the mad doctor. “But if we spin in the opposite direction, we’ll stop aging. Maybe get even younger.”
So, the doctor spun.
All day, he’d spin, which made things difficult when it came to eating, drinking, teaching classes, and going to the bathroom.
To spin while sleeping, he combined his bed and a clothes dryer.
He was dizzy, but his diapers were soft and warm.
