As far as Marx Brothers movies go, this was rather not-marvelous. Note: that's only in comparison to their other movies, it's still pretty darn entertaining. But certainly not one of the best. Glad I saw it but I wouldn't run out and buy it any time soon.
Favorite quote (sounds like something I'd say, hehe):
"You love your brother, don't you?"
"No, but I'm used to him."
