There's a real estate agent in Scottsdale, Arizona that couldn't leave an open house because a rattlesnake is blocking his exit. It's in the middle of the porch and looks ready to take a strike at him. Its rattler gets louder when the guy talks or changes positions.
He tosses a couple of rugs at it, but it won't budge. It doesn't even flinch. Eventually he had to call animal control.
