This sign is at the Macalester College library in St. Paul, Minnesota. Max is well-known on campus, and everyone likes him. He only looks grumpy in the drawing because he's not allowed into the library. Several college students recognized the sign and told us more about Max. Nicolaskg said,
The library isn’t the only place on campus Max visits. A few weeks ago, Max got into our science building and wandered into my class. Our prof laughed it off and tried to continue her lecture, but with no success. All the students were distracted with Max prancing around trying to play with everyone. Eventually after 10 minutes, Max got bored and left to presumably interrupt another class.
He has also snuck into our humanities building and even into my dorm building. It’s a tradition now to snapchat “Max spotted” if he’s seen on campus.
If you are lucky enough to meet Max, it is delightful. He is one of the friendliest cats I’ve ever met.
Keep doing you, Max, you little rebel.
Then uncle2fire posted several pictures of Max.
Why was Max banned from the library? We don't know, but it might have something to do with those books he never returned. -via reddit
