Dolphin Training Skills

Listen here, you chucklehead. You posted this 'joke' thinking it was funny, but I bet you don't even understand it. The 'joke' implies that dolphins are smart because they can quickly train humans to feed them fish. This is a reversal of the common idea that humans train animals. The humor comes from the idea that a supposedly less intelligent creature is training a human. Pretty basic stuff, even for a human like you.
