After hearing that Nero had succeeded in holding a weapon while wear a towel, Ron immediately tried it.

And just like Nero said, Ron's weapon didn't fall out of the towel.

Ron: Wow, I can't believe I've never been able to do this for so long.
Nero *laughs* : Ha ha... You see, now we can act without having our identities discovered.
Ron *nods* : Thank you, Nero. I can worry less about being in the news now.
Nero: And now we have a slogan !
Ron *excited* : Can you tell me what that is?
Nero: Then... 3... 2... 1...

IT'S TIME TO WEAR TOWEL AND BRING ME ON!
