Marginally-A-Rita

"For years people have been perfecting the margarita," begins the ad for Bud Light Lime's Lime-A-Rita, suggesting that long evolutionary process has finally reached its culmination in a canned beverage made not with tequila (who knew the secret was ditching tequila), but terrible light beer instead.

Ice, salt, and anything more than the hollow vestiges of a soul are also optional, and sold separately.
