Now, when my cousin told me about this video and that it was funny, I thought it would crack a smile and maybe get a "heh heh" at best..
That said.. upon viewing this, I had that response for maybe the first 5 seconds. By one minute I was crying, unable to hold my own weight, on the floor clutching the couch, runny nose, stomach muscles clenched, hardly breathing -- from laughing so hard, quite possibly the hardest I've ever laughed in my life. I'm sure it was a right-place-at-the-right-time thing as a second viewing resulted in massive lols, but not quite as intense as before. However, for what it is.. absolutely hilarious.
p.s. no video description on purpose, saying what it is would lessen the funny before it even starts, but I promise it's work/school safe, so long as you don't mind people turning around to find out what the hell is coming out of your computer, because it's more audio than video.
