Why does it have to be like that, G-Wiz?

After faking nice, the Washington Wizards mascot, better known as G-Wiz, played an evil trick on Bulls center Robin Lopez.

The mascot flipped a card that read "best friends" and pointed at Lopez to the backside, which instead had "nose picker" written on it. Ice cold.

But when you mess with RoLo, you're going to pay the price. Lopez, who is known to chop it up with mascots on more than a few occassions, put G-Wiz in his seat with a heavy push. For good measure, he then stomped G-Wiz's sign into oblivion.

You come at the king, you best not miss.
