From Muppet Wiki

Neville is a middle-aged British homeowner in The Great Muppet Caper. The proprietor of the house at No. 17 Highbrow Street, Neville and his wife Dorcas have their stodgy dinner interrupted by the arrival of Miss Piggy, sneaking in to convince Kermit the Frog that she (posing as Lady Holiday) lives there. Neville is finally roused from his stupor to pursue the intruder, but winds up recommending a restaurant instead.
