Off the Mark: Bryan didn't realize who was following him.

Off the Mark is a really solid single-panel gag cartoon that I rarely talk about but usually enjoy. Today's installment uses both Twitter and a pun in service of a joke, which normally wouldn't be a good sign, but Mark Parisi manages to pull it off.

The cartoon works because neither Twitter nor the pun are the joke in and of themselves. Rather, they sort of each work as a set-up and a punchline at the same time; the tweets set up the pun, but the pun does just as good a job setting up the tweets. And what's really funny about the cartoon is the situation.

Which makes sense, given that single-panel cartoons tend to live or die by the absurd situations they depict.
