Hilarious and Terrifying

I use both adjectives because watching this video below is hilarious, but if I were one of the victims I would probably s%^t my pants.

The backstory is that the Houston Rockets have an inflatable mascot that will remain motionless for minutes at a time, then spring to life on some poor, unsuspecting bystander with - you got it! - hilarious and terrifying consequences, depending on your point of view. Enjoy!
