14. Wayne's World - Pizza Hut, Doritos, Reebok, Nuprin and Pepsi
This is one we wrestled with including because it's primarily a send-up of lousy, blatant product placement in films, and it's also freaking hilarious. However, one can't forget that the filmmakers were surely still paid by Pizza Hut, Pepsi, Reebok and so on for this brilliant skit, and its hilarity has likely only made it - and indeed, the placement of the products - more memorable to viewers, so it's sort of genius really. Mike Myers' mugging in this scene is great, but try and keep a straight face once we cut to Dana Carvey's Garth, fully decked out in Reebok hockey gear, decrying people who only do things because they get paid. Priceless, or indeed, not.
