Jarvis' parents and younger sister are sitting in the background in the series' first 90 seconds then never referred to or seen again.
Some of the actors from Dan Signer's other show Mr. Young appear on this show such as Paula Shaw (Mrs Burns), Milo Shandel (Principal Tater), Emily Tennant (Ivy), Gig Morton (Derby) and Raugi Yu (Dang).
Look closely at the backgrounds during the stop-motion animation in the opening credits and you'll recognize by the props that each scene takes place in that character's part of the office.
The only episode of the show where there isn't a Knick Knack commercial before the end credits is S3 Episode 13: "Mmmmboing"
Kolton Stewart (Jarvis) is the performer of the opening song, 'Here we go'. He is also a well known singer who has found the respect of Justin Bieber. This is no surprise due to the fact that Kolton himself, like Justin, is Canadian, hence why the show is made by the Canadian TV show company.
