I honestly had no idea that Whose Line Is It Anyway? was still on the air, but apparently it is and Rob Gronkowski was a special guest on a recent show. And it was hilarious.During an improv singing number, host Aisha Tyler welcomed Gronk to the stage where he proceeded to dance awkwardly, practically throw Wayne Brady off the stage and then bench pressed comedian Jonathan Mangum.

But you really have to see it for yourself...
