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!!
The Mirage Resort and Casino held a birthday party for Roy Horn of Siegfried and Roy.
They celebrated in Siegfried and Roy's Secret Garden and Dolphin Habitat.
In attendance, other than the illusionists themselves, were some dolphins and a giant white tiger cake.
Check out some pictures from the event below.
