IT'S A MAD MAD MAD MAD TOOBWORLD

I was watching some of the New Year's Eve marathon of 'The Joey Bishop Show' and in the episode "My Buddy, My Buddy", the guest star was Buddy Hackett as himself (with Danny Thomas as a surprise guest cameo.) 

Buddy was going to be on Joey Barnes' talk show that night and during his introduction Joey talked about how Buddy had been busy the last few months making a movie: "Mad, Mad, Mad, Mad World". (Joey never said "It's A".)

So in my little fantasy realm of "Toobworld", the movie is acknowledged as actually existing. Of course, the televersion may have some differences from the real version.  Some other actors, perhaps, or a few different plot elements.

Here are some references from other TV shows:

Mad Men: The Good News 

(2010)
The movie is one of the ones that Don and Lane are contemplating seeing.

Cold Case: November 22 

(2009)
Sharon tells the police she was watching this movie when the usher announced that JFK had been shot.

Remington Steele: Steele in the Chips 

(1985)
Steele remarks how their pursuit of cookies is similar to the pursuit for an object in this film.

Remington Steele: Steele Among the Living 

(1983)
Mentioned in the dialogue.
