Groucho was like the Will Rogers or Mark Twain of his time and had that whip smart wit. When he hosted You Bet Your Life back in the golden days of Black & White, he’d call on audience members for some back and forth banter.
One time he had a man who said he had X number of kids and grandkids and Groucho said something like: "I love my cigar but I take it out of mouth every now and again."
I believe he was sued by the man for saying that.
All the best,
