Obsession

Listening to a ventriloquist on the radio?
From Woody Allen’s Radio Days:

While uncle Abe loved the "Bill Kern Sports Show" on Radio his wife Ceil adored
a very prominent ventriloquist.
And this always used to drive Abe crazy.
Abe: “He's a ventriloquist on the radio. How do know he's not moving his lips?”
Ceil: “Who cares? Leave me alone.”
