I'm in my early 30s and was carded buying a drink at a theater bar a few weeks ago. It was the first time I've been carded in at least two years.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body

You do realize that if someone has to explain a joke all humor is lost. And, why the hell would you (or anyone for that matter) wanna get drunk at a show. Drinking is the only way I can deal with your stupid posts and question by the way, and I am well above the legal age.
When a homosexual male celeb for instance doesn't want to / can't come out and doesn't want the public to suspect anything he shows off a girlfriend he is only dating for publicity. The girlfriend is what people call a "beard".
This doesn't only apply to celebs but that was just an example.
