Public Library created and shared a hilariously unhinged promotional video [featuring a trust fall gone wrong] that has been viewed by millions. It was so unexpectedly dark, but in the most delightful way, and it had people howling. But New Berlin isn’t the only library to post a cheeky promo video. Check out North Little Rock (Ark.) Public Library System’s video about people ‘literally knocking down’ their door to get a library card, or watch a librarian swipe a water bottle out of someone’s hand at Marysville (Ohio) Public Library.”
