Am I missing something in finding this presentation completely underwhelming:
Perhaps if he were to, say, guess not his own answers, but someone else's? I've always found a performer predicting his own responses to be a bit weak. No such thing as bad magic, only bad performers, of course; but, still.
The pitch amounts to his showing a card with "4" written on it; then, another with "chocolate" written on it -- both, granted, after he "asked" himself to provide a response; and finally some non-specific effusion about it being "awesome." That's it. Is this capital-s, System, so "awesome" that an actual performance is too risky? Not worth doing because a pretend performance is just as good?
Friendly advice: You'll sell more if the main pitch for your product isn't so ripe for ridicule. The thing might actually be good, if it's as described; but this clip is comically horrendous.
