To be honest, I thought it was funny.  Tax season is a long, stressful stretch of time.  Sometimes you have to lighten up and smile once in a while.  If not, you run the risk of ending up in a rubber room someplace counting license plates without ever actually being able to see a car. 

As a side note, for those of us that have been around here for awhile, we see this question getting asked at least a couple of times every year so folks somehow figure out how to get a signature to file the return.
