Marty Funkhouser (played by Bob Einstein) is one of Larry's oldest friends. He considers Larry to be his best friend although Larry begs to differ.

A self-described "orphan," Marty lost his parents in death a year apart when he was about 65.

He has a wife, and one daughter Jodi, who is a lesbian. He also has a cousin who is a dentist.

He is often very methodical about most of his actions and puts great emphasis on family. Despite that, he has been known to take credit for things that don't apply to him.
