We don’t know about you, but we’re pretty tired of singing two rounds of “Happy Birthday” or counting Mississippi to 20 each time we wash our hands. It’s difficult to do it without thinking about the reason why, and that’s not good for positivity. If you’d rather have your spirits …read more

Watchman Watches You Watching Him Watch You

At this point, society has had over three decades to get used to the Blue Man Group. Maybe that’s why we’re less disturbed by [Graham Jessup]’s face-tracking Watchman than we should be. Either that, or it’s because it reminds us of Data from Star Trek: The Next Generation. Frankly, …read more
