If you are regularly asked where all the biscuits have disappeared to, you can now simply say: abducted by aliens! The UFO Cookie Jar serves as proof, clearly showing that all the sweets were beamed up by the flying saucer.

By the way, you should really pay close attention to what you put in the jar. Some things vanish into “thin air” much more quickly than others. Reese's Pieces are particularly popular with extraterrestrials with glowing index fingers, for example... ;)
