Charlie pretends to be a dentist though he is only his assistant. When a patient can't stop laughing from the anesthesia Charlie knocks him out with a club. He is sent to the drug store, gets in a fight with a man who (after a brick in the face) becomes another patient, and pulls the skirt off the dentist's wife (who is out walking). At one point Charlie pulls a tooth (the wrong one) using enormous pliers.
