This totally made my day! John does the voice of one of the squirrels in a season two episode of 'American Dad.' He does some other voices in the episode, but I can't find it online anywhere. It's called 'Irregarding Steve.'
Dwight (Rainn Wilson) from The Office and Dina (Lauren Ash) from @Superstore share a striking amount of similarities. What if Dwight and Dina had a kid!? Oh dear god.
