Phil is Rachel Taub's boyfriend. He was originally an unseen character, but was seen for the first and only time in the Season 8 episode Parents. He is portrayed by actor Mark Atteberry. After Rachel finds out about Taub's affairs, she finds an online support group and starts exchanging messages with Phil. Taub finds out about it and realizes that Rachel is discussing things with Phil she won't discuss with him. He doesn't so much mind her venting about his affairs, but she's also telling him trivial things about her life (like her family's upcoming birthdays) that she also doesn't discuss with Taub. She makes the excuse that Phil is easier to talk to and that Taub doesn't like to listen to those things anyway.
