Packing is a good opportunity to throw away things you don't need anymore and keep... well, keep the things you keep.

Some things I threw away:
Dart board (the actual darts have been missing for years)
Fez
Assorted fortune cookie fortunes ("You will soon be on a secret mission of the heart." "It would be good to treat yourself to dessert.")
Laser pointer

Some things I kept:
Pen that extends into chart pointer
Cleanroom bunny suit (slightly too small)
Old cell phones
'Love Boat' action figures I forgot I had
Chicken
