I set up a hummingbird feeder 1-2 weeks ago and this is certainly the closest encounter with one I've had. It seemed abnormal so I told this story to a few people. Someone at my work said that hummingbirds normally do this- in fact, they have even been known to eat the sugar water right out of one's hand.
So I have to survey the Gag community: have you ever had a close encounter with a hummingbird?
