The Cocoanuts (1929)

Other mistake: Cocoanut Hotel manager Mr. Hammer (Groucho Marx) reads aloud a telegram stating that guests will arrive on the 4:30 train. He then says, "The 4:15, eh?" and tells Jamison (Zeppo Marx) that he's going to "meet the 4:15."

Continuity mistake: As Penelope steals a valuable necklace from the adjoining hotel room of Mrs. Potter and returns to her own room, Harpo is hiding under the bed. After Chico enters Penelope's room, Harpo is shown crawling on his hands and knees in Mrs. Potter's room, but we never saw him leave Penelope's room.

Hammer: Wages? Do you want to be wage slaves? Answer me that!
Bellhops: No.
Hammer: No, of course not. But what makes wage slaves? Wages!

Hammer: Three years ago I came to Florida without a nickel in my pocket. Now I've got a nickel in my pocket.

Chico: He say six, I say seven. He say seven, I say eight. He say eight, I say nine. I got plenty a numbers left. When I start, I no stoppa for no-tin'. I go higher, higher, higher, all the time I go higher.
Hammer: Eh, you'll go higher when I get ahold of ya. Sold to Hiawatha for eight hundred dollars.
