Kevin Bridges had the people in the capital in knots as he joked his way through the 3Arena on Friday, Saturday and Sunday.
The Scottish comedian played to packed out shows each night and was met by a Hollywood A-List actor on the second night.
Woody Harrelson loves Ireland and has visited the country on numerous occasions so when he heard that his favourite comedian was in town, he thought it was worth the trip.

The tweet says: "Two legends! What a lovely surprise to see the incredible @WoodyHarrelson drop in to watch @kevinbridges86 at his @3ArenaDublin show last night. Yaldy!"
The actor is best known as the bartender, Woody Boyd, in the amazing 'Cheers' and featured in the show's 200 episodes.
He's also featured in True Detective, Fraiser, Will & Grace and in recent years has played the powerful role of Haymitch Abernathy in the Hunger Games Series.
Harrelson was once sued by a factory worker after it was alleged that he hit him with a snooker cue at a Dublin nightclub in 2001.
The actor settled a lawsuit over the claims that allegedly took place in Renards which used to be a popular spot for the rich and famous.
