Elmo's World is a 15 minute segment at the end of Sesame Street. The same one is shown 5 days in a row and when they change to a different one the only real difference is one word. (Seriously.)
It's horribly annoying, but not half as much as Zoe's World would be. Thank goodness that that never occurred to them.
It's Mr. Noodle, not Mr. Noodles.
