Most people think an octopus has 8 legs.
Actually, they have 6 legs and 2 arms. How can you tell which are the arms?
Hit it on the head. The two that go up to the head when he says "Owwww" are his arms.

Explanation
The joke plays on the misconception that octopuses have only legs, and then uses a silly, violent action to identify their arms. It's funny because it's absurd, implying that an octopus would react to being hit on the head by raising its arms.
