Having your marriage proposal cruelly rejected would be bad. Having it cruelly rejected at a live basketball game in front of tens of thousands of people would be even worse. Like "testicles caught in a piece of rusty farm equipment" worse. Take note.
This also "happened" (I'll explain the quotes below) at a Houston Rockets game. Notice Tracy McGrady's nervous, tittering laugh. If anybody knows what it's like to receive a brutal ego-ectomy in front of a stunned basketball crowd, it's T-Mac.
A similar hoax was perpetrated at a Washington Wizards game in 2004. In fact, the Wizards PR department was so geeked that they proudly issued a press release about it: "Conceived in mischief, and executed without flaw, the Washington Wizards Game Operations department pulled off the prank of the year, simultaneously bewildering and wildly entertaining thousands that could not believe their eyes."
Hoo, boy, those NBA marketing teams are some HI-larious dudes and dudettes. I can't wait to see how they manage to raise the bar from this work of genius. Staged heart attacks? Fake animal rampages?! NBA action...it's FAN-tastic!
