Stop. Do not read the rest of this thread. Go right now to Amazon or your favorite DVD seller and reserve your copy of, ta da, The Marx Brothers Silver Screen Collection (The Cocoanuts / Animal Crackers / Monkey Business / Horse Feathers / Duck Soup).
Region 1 only. Sorry, rest of world.
This means that together with The Marx Brothers Collection (A Night at The Opera/A Day at The Races/A Night in Casablanca/Room Service/At the Circus/Go West/The Big Store) you only need one more DVD to complete the 13 movie set.
And Love Happy is pretty cheap.
I expect to see Julius Henry, RTFirefly and the rest of the gang in here soon, oohing and aahing.
