Yes, lemons. Lemon anything makes me happy. And lemons -- not limes! -- in many a Corona Light and her mini-me, Coronita, has made me a happy girl over the years. I don't know if it was due to preference or personal citrus stock, but when Todd Johnston (NPHS Class of 1984 and a major 1983 crush of mine) gave me my first Corona many years later, it was with a lemon. I loved it and never switched.
It's caused me to do the same ridiculous gesture at Mexican restaurants for 20 years:
May I have a Corona Light with lemon please?
