To convince those nay-sayers I present you with exhibit A.
"Why, that's just an ordinary pumpkin." you say.
Well, my friend, that is no ordinary squash. THAT is a magic pumpkin. That pumpkin, and it's brethren on the vine, were not planted by us, but simply sprouted from the earth one day!
The only logical explanations are that it is a rogue pumpkin of the magical variety or that faeries planted the thing.
Please don't try to convince me otherwise. I'm far too smart to listen to reason :)
