Lolcat Screamer

Lolcat Screamer is a screamer video uploaded to YouTube by the user lawlcatz11 on May 25, 2008.

The video begins with a slideshow of various Lolcat memes accompanied by the song New Soul by Yael Naim. However, at around 41 seconds in, Regan MacNeil appears with a loud screech (not her usual scream). It ends with a picture of a cat giggling with the text LOL, followed by the credits.
