No, wait, that’s tequila. At least that’s what I remember the San Diego jailer mentioning. Well, and that’s about all I remember.

No, Corona is a stand-up solid consistent quality watered-down sorta western “I’ll have one of those.” beers.
And it’ll come with a lime wedge, and it’ll get stuck (by the redneck in Burley, Idaho, or the yup in Eureka) in the nose of the bottle, and, well, there you have it.
