Armstrong's first role came in the 1983 hit film Risky Business.

He later reprised his role as Booger in the 1992 television movie Revenge of the Nerds III: The Next Generation and once again in the 1994 television movie Revenge of the Nerds IV: Nerds in Love.

He currently provides the voice for Mr. Moleguaco on the Disney Channel original series The Emperor's New School. Curtis was also in Akeelah and the Bee & Max Keeble's Big Move

In addition to his acting career, Armstrong's affinity for the music of Harry Nilsson has prompted him to become an expert on Nilsson's work. He has written liner notes for CD reissues of Nilsson albums, and has been instrumental in archival and bonus track preparation for these reissues. Additionally, Armstrong is an avid fan of the Three Stooges, Laurel & Hardy, and Sir Arthur Conan Doyle's Sherlock Holmes stories. Armstrong plays a character named Snot in the animated sitcom American Dad!, parodying his role from Revenge of the Nerds. He also had a role as Double Wide in the cartoon series Stroker and Hoop on Cartoon Network. Armstrong appeared in the 2006 production of Akeelah and the Bee, playing principal Mr. Welch. He was on VH1's 100 Greatest Teen Stars despite being thirty when he played his first role. Recently, he played Mecklen, Buddy "Aces" Israel's attorney, in the 2007 film, Smokin' Aces.

In the feature film Ray, for preparation for his role as Music-Executive Ahmet Ertegün, he had the top part of his head shaved to simulate male pattern baldness. He guest starred in episode 10 - "Much Too Much" and had a much smaller part in episode 11 - "Owner of a Lonely Heart" in season two of Grey's Anatomy. Armstrong played a deejay named Jerry Thunder in That '70s Show, episode 315, "Radio Daze."
