Irish YouTuber Clisare ran into 'Frostbit Boy' on Grafton Street while filming a vox pop.
uairí McSorley, who was in Dublin following an appearance on the Saturday Night Show, was spotted on Grafton Street and asked to do his best impressions.
McSorley has a YouTube channel where he does impressions of famous stars, although he didn't seem to know of everyone - "Enda who?" - although he does think the Taoiseach is a "civil critter".
Cullen also asked him what he was up to - "some shopping with the mother" - and to "read some mean YouTube comments".
"Ah, that's not very nice, now, is it! May they be struck down with a whole pile of gender weirds(sic)".
He touched on his own "mean comments" since the clip of him went viral.
"They say it's not my own brogue, that I can't keep this up forever... they'd be surprised!"
