I haven't seen Ranma 1/2 (I will some day, I promise!!). These quotes were given to my by a friend of mine...
Kuno: "I would date with you, pig-tailed girl!" "I love you, I would date with you! I love you, I would date with you! I love you, I would date with you! I love you, I would date with you! ..." ...ad nauseum. "Pig-tailed girl I love you!"
"And besides, I'm better built..." Said by Ranma in girl form to Akane during a squabble which ensued after Akane saw Ranma in boy form. They both happened to be naked at the time.
"I wore a pink leotard to a fight once!" Said by Ranma in boy form to his father, Genma. This was said during a particularly physical argument about fighting and discipline.
"You are so uncute." Said by Ranma at various times to Akane.
"PERVERT!!!!!!" by Akane, to Ranma, many, many times...
