From CB Bears comes a goofy trio of spooks who at least are making a living, which is more that could've been said for Casper's uncles, the Ghostly Trio.
Shake, Rattle, & Roll happen to manage a hotel whose clientele, understandably, consists of other ghosts and things that go bump in the night. Roll (Joe E. Ross, ex-Hong Kong Phooey) is the chief cook. Shake (Paul Winchell) & Rattle (Len Weinrib) man the switchboard and the desk, though both are at the switchboard as "Guess What's Coming to Dinner" starts. It's a variant on the age-old plot of days gone by, in which our ghosts babysit........well, I wish I could tell you.

If any one story defined the term, suspension of disbelief, this might qualify.
