Gosh, it seems I am too busy (and too uninspired) to write anything for you this weekend, so.... here's a quick cartoon (from Fritz Cartoons).
In general, I wouldn't recommend drinking with people you don't know well, or people who appear to have supernatural powers. Or weird-looking little green f***ers who can float three feet above the floor (that's a supernatural power right there - pay attention!). It's not going to end well.
Yoda would probably pull one of those Jedi mind-tricks on the poor barman as well - "This is not the tab you're looking for..." - to skip out of paying. And eventually it will all come back on you. "Hey, the green dude was with you, wasn't he? Are you going to pay for his drinks, or what?"
Obi-Wan is a different story: the guy is obviously pure class, a gentleman. But that pointy-eared freak - I wouldn't trust him as far as I can spit.
