 The scene when Tortomon corners Davis and Veemon at the edge of a  cliff, Davis asks him to wash his hands. However, when Davis says he  does not want to be beaten up by a filthy Digimon because he is a  clean guy that was not true. Davis actually makes an excuse by  saying if Tortomon washed his hands after using the bathroom  (episode 2.22 "Davis Cries Wolfmon").
