Joseph Francis "Joey" Tribbiani Sr. is Joey's father. He owns a pipe fitting business and lives with his wife Gloria on Staten Island. Both appeared in the episode "The One With The Boobies". Joey Sr. is also conducting a long-term extra-marital affair with a pet mortician named Ronni Rapalono. Although Joey disapproves of this state of affairs, he is forced to accept it when his mother reminds him how much happier his father is now that he has a "hobby", and that their marriage is much better due to Joseph Sr.'s shame.
Joey Sr. looks like a regular middle-aged man; he is average height, is a little chubby, and his head is almost completely bald. He is quite tanned, which signifies his Italian descent.
- Robert Costanzo is the only actor besides Matt LeBlanc to appear on both Friends and Joey as the same character. (Some characters, such as Gina Tribbiani appeared on both shows, but not played by the same actor, while some actors, such as Adam Goldberg appeared on both shows, but not as the same character).
