On the twelfth day of Christmas, me_am_bizarro sent to me...
Twelve fireballzer0s drumming
Eleven supreme_nothings piping
Ten themastodons a-leaping
Nine mrs_budziszs dancing
Eight toys a-milking
Seven computers a-swimming
Six movies a-laying
Five bo-o-o-ooks
Four video games
Three board games
Two comic books
...and an art in a cs_smith.
