Has to be this Twilight clock my grandma got me when she thought I liked Twilight. Weirdly (and scarily enough) it stopped working the day New Moon the movie came out, and started working when eclipse came out. ether it foretold the end of man and it's prediction was a fail or something else.
A few others are..
-A Ouija board (randomly found it at a hippie store)
-a school copy of the constitution back from my test in 6th grade.
-A black mini christmas tree with halloween skull lights, and the ornaments being the 3 masks from nightmare before christmas, transformers, an angel, garland, three miniature spartan Halo helmets and a disco ball.
and those shaped rubberbands, but shaped like mustaches.
