In the spirit of Halloween....I bring you pumpkins! And not just one pumpkin, but the best jack-o-lanterns about 15 pages of a google image search could yield.
Bonsai pumpkin!Okay, so this one's less a matter of, "Cool pumpkin!" than of, "Wait, what?"
Anybody a Doctor Who fan? Dalek pumpkin!
Last but not least.... The Death Star!
Sorry I couldn't find any bookish pumpkins... I did try.
Credits in order of appearance... toothy pumpkin, bonsai pumpkin, Ron Paul pumpkin, dalek pumpkin, Death Star pumpkin.
