I saved the screen at the top of Yik Yak here in Madison last night.

Reddit has a thread with that joke from April 2015... the thread appears to be jokes by teenagers. There are Google hits from May and June 2015, too. Step up ya joke takin' game, WI kids.Thanks. I should have checked. Yik Yak around here is full of jokes. I guess I wanted to believe that scenario took place around here. By the way, I downloaded Yik Yak after I read that it was full of horrible racist and sexist things. I never see that here. I see, in addition to jokes, people who are trying to get up the nerve to talk to somebody they like, concern about doing well in school, and expressions of joy at having seen a dog.
