The accents embark on a wild journey from Donegal to Kerry and then stop off in inner-city Dublin. The Harfoots themselves are twee and guileless and say things like: “Put yer backs into it, lads.” One is portrayed by Lenny Henry, a great comedian and actor who deserves better than having to deliver lines such as “De both of ye, dis does not bode will” (in an appalling Irish accent). Scouring the internet, there is no evidence of any Irish actors having been involved.

Cultural appropriation is okay when they do it.
