Having a bad day? Just remember that Robin Williams visited a sex shop as Mrs. Doubtfire

Apparently before the film was announced, he decided to see just how well the costume disguised his extremely famous face—by visiting a sex shop in San Francisco.

Williams walked into the store in full Mrs. Doubtfire gear and started browsing the various items on display, asking an increasingly bemused cashier the most uncomfortable questions he could think of in that inimitable old lady voice. To Williams' surprise, the cashier did, somehow, recognize him—and curtly asked him to leave when he asked for the store's largest fake penis and some sandalwood scented lubricant.
