I am always amused by the contents of my spreadsheet when I"m done.
Box 34:
5 alarm clocks
1 container of dry plaster of Paris
16 mouse traps
3 boxes of color-changing (heat sensitive) pencils
3 spare aquarium filters
5 metric tape measures
3 packages of extra stopwatch batteries.
(there are 24 extension cords, of various weights and lengths, in my office. I had 25 on my inventory sheet but someone must have nabbed one.)
