Joe Jonas was on Andy Cohen‘s Watch What Happens Live the other night, and was asked which one of the most pressing questions of our time: Which JoBro is most well-endowed? He thought about it long and hard (heh), no doubt recalling the days of shared baths and nude wrestling matches of their youth…

“Ummmm…” he said, vamping for time….

“Well. These are Nick‘s words,” he finally answered, “not mine. But he said he was going to say me, so I’m going to say me.”

DING! DING! DING!

I knew it all along! I (correctly) guessed that while Nick is clearly the superior Jonai in almost every area, he’s probably a bit stumpy in the manhood department, whereas Joe is most likely a long, thick kielbasa (in that way that skinny boys often are).

And now we have proof.

Later, he and Andy play a game of Marry, Shag, Kill with his ex-girlfriends Taylor Swift, Demi Lovato, and Gigi Hadid. The answers may surprise you.

Watch the sexy shenanigans below.
