We should probably preface this video with DO NOT TRY THIS AT HOME.
Okay, now that that's outta the way... Tennis isn't quite as boring as golf... yea, Roger Federer is a badass, but when it comes down to it, it's still just volleying a ball back and forth. The Slow Mo Guys decided to heat up the regular tennis game with a little bit of petrol and fire, seems legit, right?
The result is a Dhalsim (obligatory Street Figher II reference) style fireball that's sure to have your competitor failing to return the volley. And possibly visiting the hospital burn ward.
