If you scroll to images 14 and 28 at the Lexington Herald-Leader's photo gallery from the Arkansas game, Kentucky's DeMarcus Cousins has a toothy grin despite getting two of his teeth chipped in the 101-70 win.
Cousins wasn't available for comment, but he's probably glad that the teeth were apparently fake, having had them knocked out before, according to teammate Daniel Orton.
"I told him later [in the game] I didn't mean to and it was all just fun and games," Arkansas' Courtney Fortson, whose elbow caused the damage, told reporters.
Another reason Cousins might be smiling? Knowing you're No. 1 must hurt so good.
