Prime Minister Enda Kenny said that Biden "seems to have an inexhaustible supply of Irish sayings."
Biden also threw in a dirty joke this time, though. See him tell it in the video below.
"There's all kinds of old Irish sayings. At least my Grandfather Finnegan, I think he made them up, but it says, may the hinges of our friendship never go rusty.
Well, with these two folks that you're about to meet, if you haven't already, there’s no doubt about them staying oiled and lubricated here.
Ladies and gentlemen, now, for you who are not full Irish in this room, lubricating has a different meaning for us all," Biden said.
