I thought it was hilarious. A great example of that dry, midwestern sense of humor that I was raised with and love. If I were to explain the midwestern state of mind to an outsider, I'd probably point to that video. It was pretty damn funny.
When I was about 8 we had a terrible outbreak of tornadoes in my hometown. I remember the sirens going off all night, my mom ushering me into the hallway after looking out the window and a seeing a fat funnel a block away from my house illumanted by lightning. It was terrifying.
The tornadoes destroyed a signifigant portion of town, and almost completely demolished several smaller villages around here. Still, I'm not irate about somebody pointing to a plastic funnel. I'm more offended by those idiots who go out and film actual tornadoes, all the while hooting and hollering and cheering as it tears through somebody's home.
Once again, some people need to get thier priorities in order.
