A flag during 49ers-Rams ruins perhaps the best interception of the NFL season by K'Waun Williams

Okay yes, sure, San Francisco 49ers cornerback K'Waun Williams was whistled for a legit pass interference penalty during the fourth quarter of "Monday Night Football" while matched up against Los Angeles Rams wide receiver Cooper Kupp.

But just like a poster dunk that's correctly whistled a charge, Williams' ensuing interception should've counted anyway.

Somehow, some way, Williams — while falling to the ground — snagged the football with one hand, and then secured it with his butt. If you think I'm being unnecessarily vulgar or childish, please watch the play for yourself.

We had the Butt Fumble.
