Turns out James Bond was a total asshat for ordering his martinis that way

Everyone knows the line. A martini, shaken, not stirred. And while alcohol in general does the same to just about everyone, that specific cocktail order made James Bond one extremely confident idiot
In honor of National Martini Day, we drank 400 chocolatinis each asked mixology experts whether a martini should be shaken or stirred, and said barmen were unanimous: Bond is wrong. Stir it, you jag
According to Andres Santillana, head bartender at The LCL Bar & Kitchen, the basic rule of thumb is to shake anything with citrus or juice in order to aerate the cocktail and get the proper texture. But when it comes to your classic martini (ease up, Cheesecake Factory!!), stirring is the way to go.

"You should feel comfortable telling a bartender exactly what you want. You know, when I get people who are like, 'Oh, but could you maybe make it a little citrusy,' or something like that, I’m just like, 'What are you asking me for?' When Bond says, 'Martini shaken, not stirred,' it’s like, f*ck, man, sure. I’m not going to question you.
Of course, Daniel Craig doesn't even want to follow the rules after they've already been broken
