Three on a Limb is a 1936 American short comedy film directed by Charles Lamont and starring Buster Keaton.
[1] Elmer, a boy scout, stops for lunch at a roadside diner and falls in love with Molly, the waitress, right away.
Molly introduces her parents to Elmer and they instantly disapprove of him due to his appearance and outfit.
Molly's father challenges Elmer's scout skills by getting him to prove he can make a fire by rubbing two sticks together.
He attempts to extinguish the fire with a hose but there is a knot in the tube which stops the water from coming out.
