I often watch The West Wing re-runs when I'm working at home and since I'm working I don't use the DVR as quickly as I would if I was actively watching the show. 

Most commercials harmlessly play in the background, however I can't help but nearly jump off the couch as soon Billy Mays starts yelling about Oxi Clean or some other home cleaning product. 

I don't understand why Billy Mays must yell at me every time he is on TV.  Also, why is this an acceptable and popular form of television advertising?

I'm sure he's a nice guy and all.  But please stop yelling at me.
