Mario Rosenstock brought the house down as Miriam on the Late Late

Comedian and impersonator Mario Rosenstock was on the Late Late Show tonight, taking on the role of Miriam O'Callaghan.

And he/she was in fine form. The Miriam impression alone was enough to entertain the audience, but Rosenstock's Gerry Adams impression thrilled everyone.

It's @GiftGrubMario as Miriam doing her best Gerry Adams impression. We're not sure what's happening but we like it! 😂 #latelate pic.twitter.com/5xTh3CmPgv

Of course, the topic of the Irish Presidency and Michael D Higgins cropped up, with 'Miriam' giving her thoughts on the man in the Áras.

The first shots have been fired in the next presidential election! ☺️ @GiftGrubMario is on fire tonight! #latelate pic.twitter.com/memJcgxdFi
