Magician Mat Franco Leaves NFL Star Rob Gronkowski Speechless After Trick

There are two things in this life you can count on from New England Patriots tight end Rob Gronkowski -- the game face on Sundays and the ability to find fun wherever he goes.

'America's Got Talent' freak-show on legs Mat Franco showed up at the New England Patriots practice facility and decided to "practice" on the big man.

The fact that there is literally NO LIMITS to the art of Magic, or slight of hand, or deception by illusion in today's world, brings you no closer to understanding of HOW IN THE HELL HE DOES THIS.

No, seriously. How in the hell did he do that? Watch for yourself.
