Apparently, the tradition at Microsoft is, on the day of your anniversary of starting at MS, to bring in to work 1 pound of M&Ms for each year of service you have.  A colleague of mine is celebrating his 12th anniversary at Microsoft today, and has set up a table outside his office with every kind of M&M I think they make--12 pounds worth!

If you happen to be in Building 18 today, stop by 1216 and grab a handful...  While your at it, tell Mike congratulations for reaching this milestone!
