I have to share this story because it's one of my favorite ones...and one that I've often repeated when talking about Mike.

I used to do the software on the phones at Nortel, back in the day.  After completing that, I would go downstairs to the lower level to the data center, where the big mainframe was installed.  This frame was about 15 -20 feet long and about 6 1/2 to 7 ft high.  (I could be way off but you get the picture - it was pretty big)  It was full of colorful wire, and all I had to do was take my little punch tool, and punch down the applicable wires so my newly configured phones would ring at the desks upstairs and we'd have happy customers.  

The data center would have tours come through periodically.  One day I went down to punch down some wires, and there was a tour.  I saw them and thought, "well, I need to be quiet doing this so I don't disrupt the tour."  I got my punch tool out, "clickety, clickety click click..."  when all of the sudden, a pair of massive hands reached through the wires in the mainframe, trying to grab at my hands and this horrible "Bwwwwwaaaahahahahaha!" roared from the backside of it.  Needless to say, I dropped the tool, I screamed like I was being murdered, and I ran - in place.  (you know, running but not going anywhere.)  The entire lower level went quiet.  I think the data servers may have even stopped running. 

Mike comes sneaking out from behind the mainframe, grinning from ear to ear and laughing.  Then he sees the tour.  Ooops.  Security came - but we were long gone by then.  We only found out because one of the Data Ctr guys told us later on. 

That Mike.  Ever the prankster...
