Actually, when I was not into magic and I watched the frisbee I liked it a lot, in fact, it was my favorite trick in that eppisode, laymen aren't trained like you are.
I do kids shows several times a year. If I do a trick that is SIMILAR to another trick one or two of them have seen before, they'll call me on it. "We've seen that one." (Even if it differs from what they've actually seen.) "I know how that's done!" (Even if they don't.) "You're gonna make that do this!" (Even if I was actually going to make that do nothing and something else do something else entirely.)
My point with the kids stuff is that children notice when you do the same thing twice...even if you change objects or patter or presentation. To say that laymen will not recognize the football trick as being identical to the Frisbee trick is just not true. In fact, I've had one guy who is not the least bit savvy on magic methods mention in my presence that it was 'the Frisbee thing regurgitated.' ...Only on the football presentation he figured out the method. Which means one of two things: It was a weak enough effect the first time that it should not have been repeated, (even with a different object), or that is was so poorly done as to reveal the method. ...Or...BOTH.
Laymen aren't THAT stupid and not even children are that gullible. Apparently, it's just The 'Loyal.'
