Statistically -- Yeah, I was covered if scales. Seriously. They're on their ankles. It's something else. And obviously -- I did that one. You made that one? Yeah, that's mine. You can tell. You're going to remember that. I believe we have established that this is a fun crew to be on set with. So why don't we find out a little secret behind the squad. A little more digging, shall we?
