Wow. I just witnessed some real stupidity. Today on the Price Is Right, contestant Jose displayed what we’re calling "bad math". After making it to the showcase showdown, Jose was forced to guess the total amount of his showcase (typically between $10-30k) without going over.
Adding up "all of it" (as he put it) turned out to be long chore. After much prodding from Bob Barker, Jose announced his total: $250,000. Mr Barker politely told him to "reconsider" his bid — probably because the showcase displays didn’t have enough digits to display such a gross over-estimate. With a tad more prodding, Jose re-estimated his showcase at $60,000.
Shortly later the other contestant smiled and promptly bid $1 for her showcase. Probably making Price Is Right history and securing her victory.
