There's still a bit of St Patrick's Day lingering in the air so check out funnyman Will Ferrell dressed in full Oirish kit singing his very unique version of Danny Boy on the David Letterman Show.
Ferrell has previously spoken of how proud he is of his Irish roots and says he'd love to make a film in his ancestral home one day.
He says that he discovered that his family changed their name to Ferrell from Farrell when they left County Longford and arrived in America.
You stay classy, Ireland.
