The dentist's waiting room is modeled after an actual dentist's office in Emeryville, CA, where Pixar Animation Studios is located.
Several easter eggs are scattered about the office, including the boy's Incredibles comic (predating the 2004 film), a Ratatouille poster (predating the 2007 film), Boo's fish mobile and teddy from Monsters Inc., the Luxo ball, and a Buzz Lightyear toy and plane from Toy Story. One can also see Dr. Philip Sherman's diploma from the "Pixar University School of Dentistry," "Gums Most Likely to Recede" award, and "Toothless Grin" award, hanging on the walls.
