parodying the campaign have been produced, but with Linux portrayed as a typical male nerd. To promote Steam on Mac, Valve made a parody with Portal and Team Fortress 2 sentry guns. After the 2007–2008 Writers Guild of America strike, the cast and crew of the American television show Numb3rs decided to parody the "Get a Mac" commercials to promote the return of the show on Friday, April 4, 2008.

The cast and crew used two hours of production time to film the 34-second ad. The Get a Mac campaign became the basis for the long running YouTube series Hi, I'm a Marvel...and I'm a DC by ItsJustSomeRandomGuy. The series took the classic superhero characters from Marvel Comics and DC Comics and compared their film adaptations.

They all start the same: one proclaiming "I'm a hero" and the other proclaiming "I'm a villain." The video was made to promote their new Mac edition of the game for OS X computers, released in February 2009. Instant Star and Degrassi: The Next Generation were in a parody where they would describe their own shows. Alexz Johnson portrayed Instant Star (Johnson portrays Jude Harrison in the show) and Miriam McDonald portrayed Degrassi (McDonald portrays Emma Nelson in the show). SuperNews! made 2 shorts based on
