Dirk Nowitzki -- Murders the 'Fox' Song

Wanna see a bunch of grown men murder a terrible pop song?

Well, you're in luck, 'cause the Dallas Mavericks just spoofed "What Does the Fox Say" ... and somehow it's more hilariously painful than the original.

Dirk Nowitzki -- along with Vince Carter, Devin Harris, DeJuan Blair and the rest of the squad -- grabbed all sorts of ridiculous animal costumes and released their own parody version of that horribly addictive song.
