I work in housing for a major university and this is not the worst “serious” poster I have seen.
Examples:
-“Don’t Force it” with an image of Darth Vader force choking someone, and a little caption that tells you to make sure you ask for consent before having kinky sex.
-“Don-Nut without consent” with a bunch of rape facts on pictures of donuts.
-“Real Princesses don’t drink and drive!” With badly cut out images of Disney characters in cars.
-“Lets Taco bout racism” with a bunch of pictures of latin American dishes with speech bubbles telling you not to be a racist.
-A breaking bad poster that told you not to do drugs (???).
-Countless (and I mean countless) boards themed around The Office, Friends, or Parks and Recreation. At least one of them was a posterboard version of “Which Office Character are you?” But was based around the strategy you use to reject drinking before 21.
