Bad Growler!

Usually Carol Anne enjoys every last drop after she stops in Socorro to refill her half-gallon "growler" jug from the brew pub. But, when I got it filled the weekend before last, the barkeep had to switch kegs when the old one ran out of Pickaxe India Pale Ale. Unfortunately, what got into the growler before the keg ran out was extremely concentrated in yeast and the resulting brown mess at the bottom of the growler turned out to be undrinkable.

Sometimes you're the bug,
and sometimes you're the windshield.
Then again, sometimes you're the windshield and sometimes you're the brick?
