Hey, adjust your busts before they combust, I took a look, allright!
Looking at the size comparisons, I'd say that two-and-a-half apples seems to be a lot more realistic of a size refference of a smurf...
Now, if you'll just excuse me for a few minutes, soo I can find a ruler, and a decently sized apple to turn that into real numbers...
And, why hasn't someone passed me some eyebleach yet? This is rather straining overhere! >_>
