I need to make inexpensive clever Christmas gifts for my co-workers!?

Two years ago, I made OFFICE MUGS. It contained pens, pencils, white-out, and candy in an office mug! Last year, I used the WHISK idea (although I also added a $1.00 lottery ticket to each WHISK). This year will be my last year (my last day is January 1,2010), because of a new position. I want to give everyone something clever yet be rememberable as my parting gift. Any ideas???
