5 Things You Never Knew About ‘Dallas’ and ‘Step by Step’ Star Patrick Duffy

Patrick Duffy, who turns 76 years old today, has been a familiar face on television for decades, first as the charming Bobby Ewing on Dallas and later, as Step by Step father Frank Lambert. Behind the scenes, he’s experienced incredible highs, heartbreaking lows and even some genuinely bizarre Hollywood moments (like having to learn to swim like a porpoise for a TV show). Duffy has Irish roots and was born on St. Patrick’s Day (March 17, 1949) — his parents even owned an Irish tavern! So perhaps it was no coincidence that he was named Patrick.
