Scrubs star John McGinley stopped by Dakota Bar in Dublin last night to pull himself a pint of Guinness - as you do.
The actor is best known for his nine-year role as Dr Perry Cox on the hit comedy series.
McGinley went largely unnoticed dressed down in a baseball cap and jacket, but the staff of the South William Street pub put him to work fairly lively.
“He lasted about an hour...we were having difficulty getting him to charge the customers,” they wrote on their Facebook page today.
John also took to Twitter to name Dublin as "The Single Greatest City On the Planet!"
It's that time of years again.
The McGinley's will be descending on Dublin, Ireland. For my money? "The Single Greatest City On the Plant!"— John C. McGinley (@JohnCMcGinley) May 21, 2015
Did we mention how much we love him?
