I saw this at the Aero in 2012 with the director and star Nick Nolte in person for a Q&A.
I have to say in modern, some comedies are too long and have to have a lot of edits. Back in the day with comedies like this, all you had to do was put a camera on a tripod and roll film. Actors back then were just funny.
There's no way a film with this plot and ends this way could be made today.
