Extreme Omnivore/Playing With

Basic Trope: A character willingly eats things not meant to be eaten.
 * Straight: Bob eats a brick or some other inedible object.
 * Exaggerated: Bob can eat anything, whether it's immeasurably large, poisonous, still living, or even a nonphysical thing, like time, gravity, or an idea.
 * Justified: Bob has a superhuman digestive system and finds most things to taste at least tolerable.
 * Inverted:
 * Bob gets eaten by a brick.
 * Bob is incapable of eating.
 * Bob doesn't need to eat and therefore doesn't.
 * Picky Eater
 * Subverted: Bob eats something he shouldn't, and promptly gets a nasty stomachache...
 * Double Subverted: Which was only caused by the hot sauce he put on the object.
 * Parodied: Bob only eats nonedible things, and normal foods don't agree with his system.
 * Deconstructed: Bob eats something that wreaks havoc on his digestive tract, resulting in hospitalization and possibly death.
 * Reconstructed: He gets better, and proceeds to stick with more edible objects (Occasionally sneaking a wood screw or a paper clip.).
 * Zig Zagged: It turns out that Bob can only eat very specific inedible things.
 * Averted: Nobody eats anything other than food.
 * Enforced: "How funny would it be if we have someone eating something like a lightbulb?"
 * Lampshaded: "What does 'inedible' mean, guys?"
 * Invoked: Someone makes a bet with Bob to see if he can eat something he shouldn't.
 * Defied: Bob is sensible and realizes that, as tasty as that folding chair looks, it wouldn't make a healthy meal.
 * Discussed: ???
 * Conversed: ???
 * Played For Laughs: Seeing what new "cuisine" Bob tries this episode is one of the main running gags of the series.
 * Played For Drama: Bob has a disorder causing him to subconsciously eat things, which he tries to get over as best he can during the course of the show.

I was going to return you to Extreme Omnivore, but I was kinda hungry, and the link looked kinda tasty...
