You scratch my back...


From somewhere on the internet:

"During observation, male chimps routinely scratched a certain spot on themselves in view of their grooming partner, usually in a loud, exaggerated manner. In the majority of cases (64 percent) the groomer responded immediately by stopping and moving to groom the exact spot the gesturer had just scratched, Mitani said."
