We’re gonna need a bigger boat. And grenades. Maybe a tank.

These are the jaws of Megalodon - a close relative of the great white shark that is, mercifully, extinct. It was much larger, as cheery naked blue man will illustrate (why do you never look to your left, naked blue man?)

It also probably had the strongest bite in history. Its teeth have left scars on the bones from several fossil whales, as well as cradling the buttocks of this slightly non-plussed Victorian gent.
