Ranma ½, part 7 number 6

Kuno sends Akane and Ranma-chan a statue of himself so they can worship it while he's out of school for three days. He's off attending a gathering for a wish-bringing sword. The sword has to be drawn out of a stone. Kuno is able to draw the sword out.

Kuno uses the first wish to be able to hit Ranma over the head with a mallet. Kuno's second wish is to have a date with the pig-tailed girl. Ranma plans to dress up as Ranma-chan to get the sword from Kuno and make a wish. Akane's worried Kuno will sleep some kind of date-rape drug to Ranma-chan and then have his way with her.

Ranma-chan starts her date with Kuno. Genma wants to get the sword first, though. Ranma-chan tries to drug Kuno but it backfires and she passes out. Kuno is very tempted to ravish her, but Genma shows up, takes the sword and makes a wish.

The wish doesn't work.
