One of his first ever jobs was working the drive thru window at the famous fast food spot, Jack in the Box.
From the story floating around, he would get bored over the intercom when taking orders so he would start using clown voices.
Apparently his boss didn't find it as amusing as Mark did, and he was ultimately fired from the job.
I’d say Mark came out on top, yeah? He still got his make good shift at the “old box” though.
