5. Ozzy Osbourne for World of Warcraft
It might be the most popular MMORPG in the world, but World of Warcraft has always had something of a reputation problem, widely considered to be the kind of game that other, more-employed dorks make fun of you for playing. Enter Ozzy Osbourne, the Prince of Darkness himself, to give the franchise a much needed dose of sex, drugs and mostly just drugs, really. And sure, it's hard to believe someone with an attention span like Ozzy's could ever complete a raid, but the Ozzman is still probably the only legit warlock to walk the plains of Azeroth.
4. Aretha Franklin for the Nintendo Entertainment System
Performing what has to be the most sentimental song ever written about Duck Hunt, Queen of Soul Aretha Franklin brings a weirdly melancholy edge to this 1988 commercial for the NES. "I've been away so long," sings Franklin, ruining what should be a pretty dope Christmas, what with the fully-loaded Nintendo and all. On the other hand, there's no telling how many absent parents were guilted into buying a NES because of this ad, so maybe it's a Christmas miracle after all.
3. Buzz Aldrin for the Commodore Amiga
As one of just a handful of people to walk the surface of the goddamn moon, Buzz Aldrin is the closest thing Earth has to a real-life Commander Shepard. So it makes sense that he would eventually release his own game, 1993's Race Into Space. What doesn't really make sense is his appearance in this ad for the Commodore Amiga alongside Tommy Lasorda and veteran congressman Tip O'Neil. Because what says "fun" better than a bunch of 60-year-olds who need help with the computer?
