The Crabs

So a female crab is scuttling down the beach when she sees a male crab, and notices that he's walking straight forward instead of side-to-side.

So impressed is she by his novel approach to life, she marries him on the spot and spends that night with him.

The next morning, as they venture out for food, she notices that he's walking side-to-side, like any other crab would do.

"Hey, what gives, I thought you walked forwards, but you're going sideways now, just like any old crab!"

"What? You think I can get that drunk every day?!"
