Answer 2

Cousin Itt
Gomez's cousin, he is a short-statured hairball who speaks in a squeaky, high-pitched gibberish language that only the family understands. None of his body other than hair is visible. In the second animated series, Itt was a super-spy for the U.S. Government.
Portrayed by:
Felix Silla (Live-action TV 1964–1966, 1977) (on screen)
Roger Arroyo (Live-action TV 1965, 2 episodes) (on screen)
Tony Magro (Live-action TV 1964–1966, 1977) (voice)
John Stephenson (Animated TV 1972–1974)
John Franklin (Live-action movie 1991, 1993)
Pat Fraley (Animated TV 1992–1994)
Phil Fondacaro (Live-action movie 1998)
David Mylrea (Live-action TV 1998–1999) (on screen)
Paul Dobson (Live-action TV 1998–1999) (voice)
Leo Kennedy (Live-real) (on screen) (present)
The second animated series introduced three new regular characters, The Normanmeyers (Norman, Normina, and N.J.), a family of "normal" people living across the street from the Addamses. While Norman and Normina are constantly appalled and shocked at the Addams' macabre behavior, their son N.J. counts Wednesday and Pugsley as his best friends, and the feeling is mutual. Norman owns and works at an underwear factory and is utterly obsessed with underwear, decorating the entire Normanmeyer house with an underwear motif, which arguably makes him less "normal" than the Addamses themselves.

Answer 3

According to the credits which rolled at the end of the show - Cousin It was billed as: Cousin It as "himself" (as a joke that the TV show did not want to admit was Cousin It wasn't "real"). It certainly made for good TV and kept people guessing who really portrayed the character.

Have a lovely rest of the evening.
