Ranma 1/2 (6)
Poor Ranma...he's really a guy, but when he gets splashed with water and turns female, our oblivious friend here can't see past Ranma-Chan's more obvious attributes to put 2 and 2 together. ("Yes, foolish! It's the same person!") So, Ranma exercises his/her martial arts skills on the face... ("kiss me, willya?")
