10 Greatest Comedic Cameos That Dominated Their Respective Films

6. Neil Patrick Harris €“ Harold & Kumar Go To White Castle (2004)

Harold and Kumar are two stoners who garnered a certain cult following and a trilogy of films. The three films were all very different, but the one thing that remained consistent in each one of them was that of Neil Patrick Harris playing himself. In Harold & Kumar Go To White Castle, Harris played an exaggerated version of himself to an absolutely hilarious degree. While out in the middle of nowhere, Harold and Kumar pick up Harris, only to discover that he's a drug-addled and sex-crazed freak. Watching Harris say all of the envelope-pushing things that he does causes much glee in the viewer, and could their quest to eat burgers at White Castle get any more bizarre? Patrick-Harris steals their car of course. By the time they finally do get there, both Harold and Kumar are penniless. Thankfully Harris shows up to save the day and pays for their meal in the end, reimbursing Harold for all of the "love-stains in the backseat" of his car. What a good guy.
