Patrick Duffy, who turns 76 years outdated at present, has been a well-known face on tv for many years, first because the charming Bobby Ewing on Dallas and later, as Step by Step father Frank Lambert. Behind the scenes, he’s skilled unbelievable highs, heartbreaking lows and even some genuinely weird Hollywood moments (like having to be taught to swim like a porpoise for a TV present). Duffy has Irish roots and was born on St. Patrick’s Day (March 17, 1949) — his mother and father even owned an Irish tavern! So maybe it was no coincidence that he was named Patrick.
