My Monster - S2-E10
Continuity mistake: In the scene where Turk, JD and Dr Cox are talking about women, and how many they've slept with, take a look at the items on the table in the background that Dr Cox was previously sitting on, they appear and vanish. Mainly the cup and napkin dispenser appears and disappears in between shots. (00:15:35 - 00:16:20)
Answer: Dan was drinking beer and Cox feared that Dan might get so intoxicated he would fall asleep and drown in the tub.
