That's how Voldemort sings the Jingle Bell (Harry Potter)

You better watch-out, and hide in a hole

I'll reach down your throat, and swallow your soul! ♩ ♫  ♪ 

Voldemort is coming to town || ♩  ♪ ♫ 

I'm making a list of people I hate
When Dumbledore died, I thought it was great ♩ ♫  ♪

Voldemort is coming to town || ♩  ♪ ♫ 

I'll sneak in when you're sleeping and draw dick on your face ♩ ♫  ♪
and if you say my name outloud I will steal your birthday cake OH.... ♩  ♪ ♫
