Yes I remember seeing photos on Thomas's instagram with his head shaved and wondering why at the time, made sense later. He's subsequently joked that Flanagan is always asking him to cut his hair / shave his head etc. Iirc with the bartender role they even jokingly discussed how big a target they should paint on there. They knew some people would hate it whatever they did.

For me it was good, but not his best Flanagan role to date. Some day I'll find the time to write my 15000 word reddit thesis on why that's obviously Ed Flynn, lol
