Mayonnaise is the name of Hypnotic Clambake's fifth full-length studio album. It was released in 2005 on Blue Button Records. The album showcases the musical talents of the band's lineup at the time. It also employs catchy, pop-format songs to explore a range of humorous topics. Typical of Hypnotic Clambake, the record wanders through a wide variety of musical genres, "from Middle Eastern spice to chill calypso style." Bandleader Maury Rosenberg collaborated heavily with guitarist/bassist Chris Reynolds on the record. Reynolds wrote several of the songs, including "500 Robots" and "Woe Is Me."
