...when your arm hurts because you've started playing Wii Sports with your Nintendo Wii 
Yesterday was a Saturday so it's no work day. I spent half the day playing baseball and tennis with my kids...Wii Sports style. And when I woke up this morning my right arm was hurting a bit. Looks like I need to go and radically do something about exercising...so my boy and I did a bit of basketball this afternoon. Hopefully that can also go a little bit into reducing that bulging (pregnant!?) tummy of mine.
I've always joked that it's only my fingers that are getting exercise the past years, and I'm actually even getting less since I switched to the Dvorak keyboard layout. Now it seems the joke's on me
