these are the funniest videos you'll ever see

My sisters and I got my mom a set of Zumba DVDs for her birthday or Mother's day (I already forgot which one) this year. While we were visiting my parents last weekend, we (Tim) tried them out.

The quality of these videos is extremely poor, but I think you'll get the idea. Try to watch them without bursting out laughing:

Good thing Tim's a good sport about these types of things...
