Ken worked with my previous boss Mark Wilczewski, who very sadly passed away last July. He shared this story at his memorial service, although Ken, Mark and I had laughed many times about this. 

Mark and Ken had a business trip where the night before they were at a spot called Bar Noir and Mark was just yucking it up with the customers staying out way too late. Ken told him before leaving, "Hey, don't forget, we have a meeting at 8am."  Although Mark knew this, his was in entertainment mode.  

Next morning Mark gets up, checks out of his hotel, is ready for Ken's NON existent meeting and rushes downstairs waiting. After about an hour starts calling Ken who doesnt answer, later to find the laugh was on him, it was just a little prank Ken was known to pull! Ken will be missed.
