If you can't wow everyone with a 4.3, then you should at least try to find some other way to make your 40-yard dash the talk of the town. UCLA linebacker Jordan Zumwalt did just that, infusing his sprint with a little profanity.
Quick, what was Zumwalt's unofficial time on the 40? Of course you don't know. I don't either, because all I remember is him saying the f-word a handful of times. But I do remember it. Mission accomplished.
