This is the 147th Valentine's Day people will celebrate with those candy conversation hearts. The messages on them are the best. Which is why people buy four million pounds of them a year.

"The Atlantic" talked to NECCO, the company behind them, and got a list of some of the messages on the hearts they've retired over the years.  

Here are the top retired conversation heart messages . . .

• HOT CHA.
• The peace symbol.
• YOU ARE LATE
• SAUCY BOY.
• HEP CAT.
• DIG ME.
• GROOVY.
• FAX ME
