Garmin at work

At my office, we recently hired someone who has turned out to be a Garmin.  This became really noticeable last week.  We had a day that was particularly windy, and he was late due to (legitimate) public transportation issues.  That started him on jokes about how he was worried that he was going to be blown away for being so little.  He also made jokes about how he might have trouble typing on the keyboard on his computer due to his small hands.  I also know that his height is 5'2" because he has brought it up several times as part of various jokes and other commentary he has made about himself.  I will spare all of you more details, but it's like this guy is trying to be a real life Garmin at maximum cringe.  And when he does this, he almost literally sounds like Garmin from the Portlandia sketch.

So far no one at my office has taken this bait.  I have worked at this job for a year and a half.  We have short, tall, and average height people.  No one has ever talked about height (as far as I know) even with the Garmin constantly bringing up his height/size.  Nobody has made fun of the Garmin's height, and anytime the Garmin has brought up his height/size it has more or less been ignored.  (i.e. On the windy day, the response to the Garmin were things like, "Yeah, I was lucky there weren't any downed trees on my way to work" and other neutral commentary.)  I'm hoping that the Garmin doesn't try to step up his Garminess to get a response from my coworkers and me.
