The TV Hat people say it's "the next revolution in video viewing". That's quite a statement for a modified baseball hat that includes a pouch for most sizes of portable video players and a built-in magnifying glass to make the picture seem larger. Some important warnings:

"Children should be supervised at all times when using the TV Hat."

"Do not wear the TV Hat with pouch and side curtains down while moving around (walking, running, driving a car or operating any kind of machinery can be hazardous...)"

Or maybe you just shouldn't put the hat on at all.
