In a 1959 interview on BBC TV's Showtime, Chico Marx explained how his brother "Groucho" got his name.  "We used to wear a little bag around our neck, called a Grouch bag. In this bag we would keep our pennies, some marbles, a couple of pieces of candy, a little marijuana, whatever we could get...because, you know, we were studying to be musicians. So that's where Groucho got his name."
