Cat Stevens taught us that the first cut is the deepest, but that was years ago and we have Twitter now. As Mia Farrow taught us during Sunday night's Golden Globes Awards telecast, it's possible to cut deep in 140 characters.

Farrow -- who dated filmmaker Woody Allen from 1980 until 1992, when she discovered that he was having a sexual relationship with her adopted daughter Soon-Yi, whom he married in 1997 -- got in an epic burn on her ex-beau when he was presented with the Cecil B. DeMille lifetime achievement award.

Farrow had been enthusiastically live-tweeting the awards ("Yay Spike Jonze" was among her astute observations) until it came time for the tribute to Allen. It was then that Farrow, who appeared in 12 of Allen's films while they were dating, demonstrated her advanced shade-throwing skills.

"Time to grab some icecream & switch over to #GIRLS," she tweeted, making no mention of her ex. Her next tweet, which appears to be her last of the night, confirmed her abrupt exit: "Nite all."

Woody, who did not attend the awards ceremony, instead opting to have "Annie Hall" star Diane Keaton pay tribute to him by singing a spooky little song, could not be contacted to see whether he needs any ice cream for the burns caused by what is possibly the greatest subtweet of modern history.
