The gift that keeps on giving

Nope.  Not talking about Herpes.  Check this out:

I assure you this is not a joke.  So pray tell...WHO and WHY?

Are you the person playing lawn games and don't want to set down your beer?  I imagine most lawn games require bending, jumping, and reaching.  So how is it this would be good for that?  Or maybe you are doing yard work?  Again, a lot of movement required.  Are you in construction and need both hands free at all times?  Not good to "drink and saw", much less hammer or climb a ladder.  I just don't get it.  Maybe you want to mow and drink?  If your lawn is sooo big you can't go the distance without a beer, then you should have a riding mower equiped with a cup holder.  Golfer?  I'm not one myself but I've seen people tee off and again, there is a lot of hip action in that swing!

So ya, I need help here.  Digame por favor...WHO and WHY?
