Betty White may be 93 years old, but she's still as high maintenance as ever (well, sort of). The actress, who recently joined Instagram, stopped by The Late Late Show With James Corden on Tuesday and made it known to the host that if she isn't happy, nobody will be. In a hidden-camera skit, Betty hilariously pranks James by calling him on the phone before her appearance and giving him a list of demands for her dressing room, including a change in lighting, a specific color the walls must be, and only wanting yellow M&M's. Watch the funny prank above to see James's reaction, then look back at Betty through the years.
