No worries, in this time of attributing all quotes to random people. I like to attribute them correctly when I can.
If you have never seen Groucho get into full swing it is worth a watch. He had a way with a line that was like no other. The Marx brothers (Groucho, Chico, Harpo, and Zeppo) were one of the few acts that were able to make it from vaudeville to cinema.
Oh and just because someone is going to be confused about Zeppo he was the straight man and wasn’t always in their films.
P.S. there was also Gummo but he never liked it and left before the transition to cinema
