Enter Robert, Lemon Tech's #1 Support-guy-who-looks-just-like-Carl-from-Spare-Parts (completely intentional, I assure you).

Modern Commentary
It's Carl.
I mean it's Robert.

So, before You Say it First started, we had a comic called Spare Parts. It starred Carl, who looks like the human version of that guy. Spare Parts was ongoing at the time and was the main comic that I was working on.
I don't remember why we did it; I think it was Isabel's idea to encourage me to write more You Say it First. - Terrence
