I'll have to check the DVD but while perusing IMDB.com I found this bit of interesting trivia:

Suzanne Pleshette, who had been friends 'with Pete Falk (I)' since she was 14 years old said that he had behaved very badly during the making of this show. In fact, she didn't talk to him afterwards for a year. She also said that guest star Eddie Albert told Falk, "I always wanted to meet you, I always wanted to work with you, but you're a real [anal sphincter]."

That is an interesting tidbit. I wonder what went wrong?

Apparently it was because of the tension surrounding Peter Falk's battle with the network to direct at least one Season 1 episode. He had admirable thick skin, and regardless of what was done or said "Dead Weight" is one of the best episodes of the entire series.
