It has also been said by a few characters that he is quite feminine, as stated in the episodes "The Wedding" and "Shore Leave", as well as accidentally placing in a tape of him dressed like a girl in "Method of Acting".
His actions often suggest that he is lonely and, on numerous occasions, attempts to organize group meet-ups with the other adult characters (episodes: Four's Company, Pizza Club) and acts desperate when they decline his invitations.
Towards the end of the episode as Brendon and Paula talk, in the background on the TV there is a wrestling match on with a masked luchador that looks exactly like McGuirk with the Spanish translation of "the soccer coach" on his costumed chest.
Jason Penopolis (H. Jon Benjamin) is Brendon's friend and co-star who is noticeably more emotionally stunted, but can be much more aware of his surroundings and situations than others.
Subtle irony throughout the series suggests that, while his parents are never introduced, they are wealthy, but never around or aware of Jason's pastimes, including the fact that he is always hanging out with Brendon and Melissa making films, though he himself is at least partially unaware that they tape them and while being friends with Brendon and Melissa, he never once told his parents about them.
He has suffered dangerous and extreme attacks of sugar addiction on several occasions that Melissa usually helps him overcome.
Jason's last name has been spelled out as Panopolis (in "The Art of the Sucker Punch" within the closed captions), Penopolis (in "Time to Pay the Price"), Popodopolis (in "History"), and Penopopolis (in "Focus Grill").
She talks very frankly with Brendon about life issues, and they both make age-inappropriate jokes, thereby creating much more of a friendship between them than is usual.
She is highly critical of Andrew's (Brendon's father's) relationship with Linda, frequently mocking the age disparity.
