Donnie has Paul put together a burger speed-eating contest at the Coney Island Wahlburgers to coincide with Donnie throwing out the ceremonial first pitch of the Brooklyn Cyclones minor league baseball team. Donnie takes lessons from the Cyclones pitching coach so he doesn't embarrass himself or the family name. Back in Boston, Bob's daughter, Charlie, asks him about their family heritage for a school project. Bob brings in Alma and Uncle Archie to talk about the two sides of the family, and takes a DNA test to find out how Irish the family really is.
