[Tinuviel the Nightingale]

I have done this many times, and I'm sure a lot of other people have as well.

Me and my friends who don't really like Lotr were walking in a park. A crow flew over my head and I screamed "Ai! Crebain from Dunlend!" and dived into the nearest bush.
I was laughing so hard I was basically rolling around on the park grass (which is unwise because there's usually lots of glass around) while my friends were trying to figure out what's going on. To this day, they still have no idea...
