"Aw, that's so cute!" isn't a phrase that is generally associated with sharks. A considerably more common one is: "Oh my God! We're all going to die!!!" Even, "Well, he shouldn't have been surfing with a cheeseburger," pops up a bit more often.

All things bright and beautiful,
All creatures great and small,
All things wise and wonderful,
Belly rubs for them all.
