Guys! You left such kind responses on the last pumpkin post! As for the question of whether it's real, and actually a pumpkin, here is an image of it alongside the one that was originally supposed to be my portrait but failed miserably. Now the latter is a slightly more traditional jack-o-lantern, although all you can see here is its gaping maw.
Oh, and here is one with flash, where the magic disappears!
It's also easier when the pumpkin wall is as uniform as possible and relatively thin--maybe an inch and a half. You want some thickness for stability, but you don't want to bury your knife to the handle and only see the very tip sticking through the other side (as happened to me when I first inherited the hollowed pumpkin from David!).
It's a bit fussy, but the results when you put a candle in it and turn out the lights are awfully nifty.
