Betty's version of "Ev'ry One Says I Love You" is yet another version of the song introduced by the Marx Brothers in the earlier film--also released by Paramount Pictures.
Groucho reminisces over the first five Marx Brothers films, which he said were produced by Jesse L. Lasky.
One of the two films that Mike (dressed as Groucho) and Gloria (dressed as Harpo) were going out to see
Crow: Anything further, Father?
Tom (in a scene at a football game): "Harpo!"
Quote: "What's the password? ...And if you say 'Swordfish' I'll lose it!"
Harpo throws the football to an opposition player in order to tackle him, just as Adam Sandler does in 'The Waterboy'.
In Horse Feathers, the speakeasy password was Swordfish, which became the most famous "password" of several generations
the title referes to the bit in the film about the password "swordfish"
Murderface references Groucho Marx's famous line, 'Why don't you bore a hole in yourself and let the sap run out?'
When Roger gives a $5 bill to the bouncer (at what turns out to be a casino) he says "Swordfish." This is a reference to the scene in Horse Feathers between Groucho and Chico Marx where Chico is the temporary bouncer at a speakeasy and Groucho uses the correct password "Swordfish" after Chico blabbed it to him.
The herbs in the film are named after the Marx Brothers and, at one point, Si quotes directly from this film.
It is one of the movie posters seen at the drive-in theater.
