The Accidental Text on Purpose - S9-E6
Factual error: Even though the exterior establishing shot suggests (and Funkhouser later mentions) that Larry's incident with the "spritzer" happened at Neiman Marcus, the scene was actually filmed inside the Saks Fifth Avenue just a couple blocks away. This is evidenced by a couple things: The gold-framed doors and gold stair railings are architectural features of the Beverly Hills Saks. Also, the sign on the display table (with the soaps and lotions) has the bolder font that Saks uses on it's in-store display signage that's similar to Gotham. Neiman Marcus uses a lighter-weighted font that's similar to Futura on their in-store display signage.
Factual error: Larry is having a MRI and he is completely clothed with his shoes still on but he took his glasses off. When doing a MRI the patient has to has to wear gown. (00:05:00)
