Forget being entertained by the sprinkling of parmesan cheese. That is so, like, last month.
No, if you want real funny, you have to say, "Ta-DAHHHH!" as if you were producing a rabbit out of a hat.
Then your play-partner has to announce "Ta-DAHHHH!" right back.
And then you both giggle like the dickens, and then do it all over again.
