James Harden's beard is so big that it houses a lot of small objects. For example: Joey Crawford's whistle, apparently.
I'd make a joke about James Harden's beard here, but I don't want Reggie Miller to kill it. (Note to Reggie: when the guy next to you, in this case Steve Kerr, makes a joke about a bird falling out of Harden's beard, it's annoying when you repeat the joke at the top of your lungs. Stop it).
