A couple of days ago I came across this comic strip.
It's about an alternate world where a human dresses up like a bot and tries to infiltrate a bot community or something, then he is blocked by a door that says "prove you are not a human: enter the value of pi".
You can see bots walking in pairs on the left of the comic, and the human dressed as bot fretting near the door as he can't remember all the decimals in pi, on the right side of the comic. In the next panel, you see him calling someone (probably a boss), and telling him "sorry, the mission has been compromised".
The comic is not so detailed as Marvel's. It's a simple one, though not as plain as The Oatmeal. It does not have stick figures, rather proper drawings of the characters.
