Don't worry about sharks. It's the spiders that want to KILL everyone. A spider once kept me on my front porch(groceries in hand) for about 30 minutes! It was jusr sitting on my door handle...just giving me the evil eye. Finally, someone showed up and killed it for me but it still sucked. I had been throwing stuff from the grocery store at it, trying to make it leave. I was throwing rolls of paper towels, a box of garbage bags, and a bunch of other stuff. My night was ruined. I'm not even gonna go into the shower/spider story.
