Generally, when I embed a video of something stupid here, I like to keep it short. We lead busy lives, and while a nice clip of someone falling through a table is all well and good, it doesn't need to be longer than say 20 seconds.
The only thing that justifies a longer viewing time is deeper levels or layers of stupidity. For example, a clip of a woman forgetting the words to the National Anthem can run a little longer if it offers some extra slippery bonus stupidity.
And then there's this clip from Most Daring,of a radio stunt gone wrong that actually offers five different levels of stupid in just one clip. Can you guess them all?
