After seeing Paul Mazursky's Bob & Carol & Ted & Alice I felt inclined to see I Love You, Alice B. Toklas! since it is also written by Mazursky. Unfortunately for me, I Love You, Alice B. Toklas! is not nearly as good, or humorous, as Bob & Carol & Ted & Alice. Sure, it has its moments but it's just not great.

Peter Sellers stars as Harold, a lawyer in the late 1960s. Harold is a square and he knows it, but it doesn't matter to him (at least not yet). He is engaged to a woman named Joyce, and he is very successful in his profession. He doesn't know it yet, but his life is about to change.

One day at the office, Harold's mother (Jo Van Fleet) comes rushing in weeping about how a man had just died. Harold thinks it's his father, but is relieved to find out it's just the butcher. It is important to his mother that Harold attends the funeral, and brings his brother along. Harold's brother is a hippie living in Venice Beach, and Harold hasn't seen him in three months but he agrees.

When the day of the funeral arrives, Harold goes to pick up his brother Herbie (David Arkin) at his apartment. Upon his arrival Harold is met by Herbie and Herbie’s lady friend Nancy (the lovely Leigh Taylor-Young, who you may recognize as Shirl in Soylent Green). Herbie looks ridiculous, as he's dressed in traditional Hopi Indian funeral garb and this upsets Harold greatly. This is not something a normal person wears to a Catholic funeral, but there's nothing he can do.

The funeral is one of the more humorous scenes in the film. The hearse drivers are on strike, so there is no way to get the body from the funeral home to the cemetery. Harold is the only person in attendance with a station wagon, and it's a loaner that he had to take after his Lincoln was hit. The wagon is painted up and down with rainbows and peace signs; it's really a sight. Harold volunteers to transport the body, and the procession goes on its way. Unfortunately, Harold gets pulled over and loses the procession and ends up driving around for hours trying to find the cemetery.
