Some friends of mine in band and I actually had a discussion about this around midnight in an ihop we were eating in after a pep band in fall break of 2015 actually-basically we came to that conclusion that it's fairly typical for that to happen when we're extremely tired, especially between about 11:30 and 12:30. We also managed to creep out and/or confuse the workers there several times probably with some of our shenanigans. =P That was a very fun day, with a lot of random music we'd played through with a weird instrumentation.
