Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
A man in Australia named Stephen King was surfing when suddenly, there was:
"[…] a bang from the side and I went cartwheeling through the air, then there was this thrashing beside me."
That bang was a shark taking a huge bite out of his surfboard!
Good thing he wasn't Stephen King the author or else the surfboard would probably have turned into a wereshark and attacked him or something.
