I think a few of you have already stumbled upon Cornify, the website that allows you to cornify just about anything. Like The Modern Gal ...
Try it. I dare you.
Let me also introduce you to the Lolinator which allows you to apply a laugh track to any You Tube video.
Try this Lolinated video on for size. (Make sure you hit 'Play' when you get there.)
If you're a really big nerd, you can also Benny Hillify your You Tube videos with the Benny Hillifier by adding the Yakety Sax track (and by speeding the video up really, really fast). If you don't know Benny Hill, don't worry about this one.
