A few years ago, my favorite morning show 'Dave and Darren in the morning" (now a podcast called Dave and Darren's Top 5 things) got cancelled. They were the victims in the new owners reformatting the station to country geared to younger female listeners (that station did not last long).
After their no compete clause ended, and the amount of listener support they received, Dave and Darren started a podcast. A common thing Dave would say concerning the station and the station's programing choices was " We wish them nothing but the best". It was complete sarcasm. Since then, I always took the phrase 'wish them nothing but the best' as complete sarcasm and meaning nothing close to truly wishing them the best.
