7. Tiger Woods PGA Tour 09 All-Play
Before Woods' private life became very public, one of his stranger controversies involved this seemingly innocuous trailer, which seems to show him playing the Wii version of his 2008 golfing sim – but that's clearly not Wii footage playing behind him.
It's actually from the Xbox 360 version of the game. One complaint from a UK viewer triggered an investigation by the Advertising Standards Authority over there, which concluded that the ad was misleading and banned it from the airwaves.
