Donald Trump is trying to trademark “You're Fired”, the signature line from his reality show (which I personally don't watch).
The thing is, I think we have some prior art involved here.
Remember True Lies? At the end of the movie, when the lead terrorist is hanging from the Harrier missile, the Governator shouts “You're Fired!” and then promptly fires the missile. (Quotes page at IMDB).
(I'll let you know next year what this all means when I actually take some Trademark classes :)
