Edit: vegetable --> plant, and if I win (we can agree on some defined objective comparisons and scoring offline) I'll even donate the money you'd have repaid back to the charity of my choosing. I'd be glad to make our miminal findings public as well.

Unless you're willing to engage in a 6-12 month comprehensive study of messageboard thread challenges, which we will cofinance (but in the end, if we find that these types of challenges are generally accepted as arguments, I'll compensate you for your half of the research budget, and vice-versa), you must concede that that's a silly thing to wonder about...
