Legendary director Woody Allen had kind of an awkward Father's Day yesterday after his estranged son ripped him on Twitter with a joke about Woody and his wife.
When your wife used to be your stepdaughter, you're sorta asking for it.
Ronan Farrow, the 24-year-old son of Allen and Mia Farrow, posted on Twitter, "Happy father's day -- or as they call it in my family, happy brother-in-law's day."
Mia Farrow then re-tweeted the message ... and added the word, "BOOM."

According to reports, Ronan stopped speaking to his father back in 1992 when it was discovered Woody was cheating on Mia with Soon-Yi Previn.
That would be Mia Farrow's adopted daughter with her second husband, André Previn. Woody began dating Mia in 1980 when Soon-Yi was 10.
Fun fact: Ronan is a well-respected human rights activist, freelance journalist, Rhodes Scholar, lawyer and government official at age 24. Impressive.
