... what?

I was at the 7-11 near my home, when I heard some commercial for some cartoon, and they used the most idiotic catchphrase ever.

"THE SHOW ISN'T OVER TILL IT'S OVER!"

Like, duh. I'm not dead till I die. It doesn't even sound cool. You'd expect something like "The show isn't over till [insert something negative happening to the other guy]" or "The show isn't over till [insert claim of victory here]". I mean, SO WHAT if the show isn't over till it's over? If the bad guy wins, the show would still be over. It's not like as if that sentence is saying "You're not going to win". All that sentence is saying is nothing. It is the single most redundant sentence in the world. If I was in a competition/fight and my opponent said that to me... oh god, the things I would do to him. After I laugh in his face for 1 hour.
