hmm... chewing cards... i'll give that a shot with some old TCG cards i have... (i'm talking good ol' yugioh, take one of those ancient miscolored cards...)
here's a reasonable scenario parent- 'what are you doing!?!'
you- 'i'm expanded my horizons for foods that i like.'
parent- 'but why?'
you- 'well, say you're to hungry to actually cook the food, just eat the box as well, plus, the fiber is good for you.' XD
