[Freddy Krueger enters my dream but I'm blasting Rebecca Black on repeat] Who's nightmare is it now Freddy?!

Yo mama is so ugly that she gave Freddy Krueger nightmares.

Why was Freddy Krueger late for work? Cause traffic is a nightmare on Elm Street.

What song does Freddy Krueger listen to when he gets a manicure? I got Kniiiiiives on it! that inspired the joke.
