Sisto 

Sisto is the type of guy to break your heart unknowingly. Or, sometimes he will but you’ll never really know what he’s thinking or feeling. An overall great guy, very attractive and tall but will not hesitate to drop you and leave you. He’ll talk to you for a little, then end up finding someone better and ghosting you. Of course he’s a high school jock... he’s used to being hit on and taking advantage of girls beneath him.

Girl: Sisto said he was going to bed but stayed up talking to that bitch Bethany!
Girl 2: You should’ve known that he was a heartbreaker.

Sisto 

The younger brother of former space pirate, Brak. Long ago he was Brak's second in command, helping him commit evil insidious acts, but radiation from a meteor shower had riddled them harmless. While Brak became retarded, Sisto became mute (though he tends to respond with to people with fart noises).

Though it is still uncertain what species Brak and Sisto actually are, their kind have been refered to as catmen on numerous occasions. Though the two are almost identical, Sisto is much shorter and wears a red uniform in contrast to Brak's blue uniform. Supposively, he was killed off in ep 18 when aliens beamed him up as their chosen food source.

Dad: "Do I smell the stink of Jealosy?"
Sisto: *farts*

Plump Sister 

A woman who has put on a few pounds since the last time that a random 72 year old Uncle will say to Larry, the cousin twice removed, this kind of thing:

Uncle: "Golly! That's Suzanne? She has gotten to be a real Plump Sister since the last time I saw her."
Larry: "Must've been back in the Seventies. Before the kid. Kids. Who knows."

Uncle: "It was May 1979. When they got married...wow she just blimped out!" Larry: "Total butterball. Plump Sister, shame."
