If you ever get a chance to take a half-court shot for $50,000, here's some advice.  Make sure you know the rules first. Yesterday at the Missouri Valley basketball tournament in St. Louis, a guy named Alex Permann had a chance at 50 grand, but he didn't just have to make a half-court shot.  He had to make a lay-up, then a free throw, then a three-pointer, THEN a half-court shot, all in less than 25 seconds.  Well, Alex made THREE of those shots, including the one from half-court. But he forgot about the three-pointer . . . even though the announcer and people in the crowd were yelling "three-pointer" at him.  After the game, he admitted that he wasn't clear on the instructions, saying quote, "I was so excited to be out there that I didn't pay attention to what [the announcer] said.  I had in my mind what I was going to do."Luckily, he's not walking away completely empty handed.  He DOESN'T get any of the $50,000. But he does get free tickets to the Missouri Valley tournament for life. Plus, some V.I.P. passes, and three days in a hotel for next year's tournament. Which, let's be honest . . . totally sucks compared to 50 grand.
