A very indirect version happens in Dragon Ball, during the first Tournament Arc. Master Roshi hypnotizes Goku to sleep, as a major desperate move. Later, Roshi claims that there is no stimulus to wake up Goku before he gives a proper sign, though Bulma realizes that there's one thing to get through to Goku, she announces its dinnertime, he immediately wakes up.
This trope was played in K-On! - The girls were trying to wake up Yui, by claiming that they bought her cake. But she went back to sleep when she notices that there's no actual cake.

In chapter 9.6 of Descendant of a Demon Lord, Celes wakes up by lowering a live mole attached to a string towards Lady Slaughter (who was sleeping in a crevice). Yes this counts.
