Legendary comedic actor Harry Shearer celebrates his birthday today (December 23), and while most know him as the voices for Mr. Burns, Waylon Smithers, Principal Skinner and Ned Flanders on The Simpsons, he’ll always be Derek Smalls, bassist for Spinal Tap.

When it comes to the iconic mockumentary This Is Spinal Tap, there are so many hilarious moments that come via Smalls, but the metal detector scene is just perfection.

For real, why on Earth would you wrap the cucumber in foil and then stuff it down your pants?!  Love to know if anybody pulled a similar prank on airport security since the film’s release.
