I'm watching last night's episode of Monk - Mr Monk and the UFO. Mr Monk has just been asked where he is staying while in Nevada and he replies "at the Sleep Inn" and I had a little giggle to myself because I thought this was one of those crazy made up things they put in TV shows and video games (like Pro Laps in Grand Theft Auto). Pretty witty I thought. The next scene comes on: Is that the ® symbol there? Yeah, it is. I googled "Sleep Inn" and it turns out it's a real hotel chain operating in the USA. This is incredible to me - the main character has mentioned the company's name AND its main 'product' has now appeared prominently in the middle of the screen. Why is this legal in the USA?
