1) i always figured that the candy corn teeth would be maleable, pliable, liable and undeniably modular. but i only considered switching them with other flavors, colors and holiday candy corns (the xmas candy corns, and the easter candy corns). sure ill look fesitive for all hallows eve but i think it might look in appropriate under certain circumstances (ie business meetings and funerals).

2) i couldnt think of a single PRO to the tin foil skin...i mean like you said, it rips, tears, rusts, crinkles and lets not forget about airport security screening complications. sure you could be a street performer doing that statue of liberty of tin man mime shit but really, at the end of the day, nobody respects those guys.
