Tarzan of the Apes -- 1931 or so. Johnny Weismuller wrestles Maureen O'Sullivan to the ground and tickles her foot while she complains "Tarzan, you're tickling, stop!"
Tarzan of the Apes -- dreadful, godawful 1959 remake of above. Better foot views and tickle action by far. Virtually the same scene, dialogue a little different. Don't know if it's rentable, but TBS shows it occasionally.
