The best kind of movies to Riff to are sex ed films. I put one of the best classic Sex Ed Riffs on the line so watch it for a lot less than the proffesionals prices for the same laughs. As Boys Grow is a classic film from the 50's and it is perfect material that I have honed for a masterpiece of laughter. Join the masterpice so you can become one with laughter. I have spoken. Seriously feel free to comment and please rate my show. This movie is 16 min. and 17 sec. Enjoy it.
