College kids today have way too much time on their hands. Take, for instance, Savannah College of Art and Design student Bang-yao Liu. Not content with leaving Post-It notes for his roommate like, "If it's brown, flush it down" and "I accidentally took all your Penicillin last night thinking it was E," Bang-yao Liu turned a wall into a Post-It Note stop-motion masterpiece. According to AdFreak:

The two-minute clip required three months of planning, four days of shooting and more than 6,000 Post-its.

The greatest (and most effort intensive) thing I did in college: convincing two chicks to make out with each other at the Sand Bar.
