I'm all for quest givers getting drunk, passing out & joining TEST while their sobriety is on vacation as long as they continue to be a good TESTie once they recover from their drunken stupor & potential hangover.
Clearly this is neither our glorious leader Montoya nor the seemingly omnipresent Blind Owl. Montoya's supreme self would never land on the floor like that no matter how much he had to drink. The floor would levitate him for the glory of TEST Squadron so that it would not be in violation of soiling his clothing.
As for Blind Owl, I suspect that instead of ending up in positions such as this, he would pass out in an upside down, meditative, lotus pose while still managing to never spill a drop of his beer as his sleeping body continues to drink on its own. Quite the mental images I would say.
