Going back over old episodes of Friends, viewers are always noticing things that don't jump out the first time around and one viewer has now spotted an Irish reference which may have gone over your head.
Posting on Reddit, thegavin shared an image of Ross Geller enjoying a bottle of Harp Lager while sitting at Monica and Rachel's kitchen table.
The original poster commented that the still is from the season four episode The One With Joey's New Girlfriend which featured the subplot of Ross and Rachel attempting to make each other jealous with their new relationships. Yep, that's the one in which Ross was secretly babysitting for his new 'girlfriend' while Rachel's new beau was stealing from her.
Nothing like a bottle of Dundalk's finest to wash down all that embarrassment.
