Beer Bongs?! How old are we?!

Our neighbors, the Emerys, had some friends in town from Tennessee and they needed to borrow one of our Wii remotes. So Casey and his friend came over to get the remote and brought a beer bong with them. Hilarious!! Apparently they always make a beer bong when they get together, some tradition I guess. So anyway, they took Randy outside and had him try it out. I was quite impressed with Randy's skill. They tried to get me to do it, but I refused. Just curious... how old are we?!
