Dick Van Dyke is suffering from an as-yet "undiagnosed neurological disorder" and has been advised to rest and avoid plane travel until doctors know what the veteran showman is dealing with, according to his rep.
"My head bangs every time I lay down," the 87-year-old said Wednesday on Twitter. "I've had every test come back that I'm perfectly healthy. Anybody got any ideas?"
The tweet sparked dozens of responses, some serious and others joking. Comic Elayne Boosler advised him against sleeping on the drum kit.
One immediate effect of doctors' advice was the nixing of a trip to New York next week to receive the first Lifetime Achievement Award for Bettering Humanity Through Comedy from the 92nd Street Y.
