Forget the rooting for multiple teams topic. There's something else here that's much more interesting.
Check out these pics. Notice a common theme?
Family lamp that still works from the mid 80s? - Check (BTW, sweet CD collection)
Sound system picked up from Target so he can jam out in his room? - Check
Chair & drapes passed down from Grandma to the family? - Check
Last picture taken from mom & dad's room. - Check (also note the neighborhood. Looks like this tough guy is really roughing it in the hood)
So the question really is...
When is it too old to still be living with your parents?
