Tayfun told me the funniest thing.
Did you know, that hollywood has a little inside joke toward all us movieviewers?
A movie director came to his school for a workshop, and told the class
a little something called the ‘Wilhelm Scream”.
It’s a stock sound effect, first used in the movie ‘Distant drums’ in 1951. 
Named after the Character that first used it.
By now, it’s been used in almost 300 movies, and no one knows it!
Not unless you’ve heard it and recoqnize it.
Its so funny.
