My wife can certainly heft and bring home the keg. I'm not sure I wanna jump through the hoops necessary to access the keg if she does so though, which is why I pay others for delivery and set up. ;) (which stands for ULTRA wink. an emoticon that has yet to be invented)
My wife wouldn't carry a pepper pod for me much less a keg. Now if the keg was full of some kinda fruity beverage so sweet that you couldn't taste the alcohol....
Hah!!
I would be carrying that too
