Ever wonder how to handle those embarrassing moments in class? Here you are showing a great posting on You Tube. It's a perfect fit for what you are teaching -- you may have even made the post yourself and then someone giggles about an inappropriate ad on the side margin.
The ads adjacent to all of the online materials you use in class are often part of cognitive overhead but they simply don't register or become part of the attention in a lesson. However, there are times when an ad is just too funny, placed alongside a lesson, to be ignored.
An alternative site that you can use is Teacher Tube. Our experience is that it is safer for focusing attention on what you want students to pay attention to.
