That's right, the owl is a fan of absinthe. It's a horribly overhyped drink, its mostly just a herbal liqour, not unlike ouzo, except for including a crap-ton of alcohol, which is always a plus (and possibly wormwood, depending on the kind).

However, I like the slightly bitter liqourice-esque taste of it, and the mythlogy surrounding it is pretty cool too.
