Oliver Callen Nob Nation Late late show 

A fantastic performer. Looking back, he could have done a few movies...There's still time.

His David Norris is fanflippingtastic.

I'm going to the late late show tomorrow. I cant wait

Fantastic Irish comedy.

Very good Enda Kenny

I was reading somewhere, their is riverly between Oliver Callahan and Mario Rosenstock.

Brilliant! 😂😂😂😂

He's the spit of Simon Pegg

in fairness i use to think mario was better but now i think they're both as good as each other. both do very good impressions!

Yes he is, thumbs up id you agree

Brillant🤣

Mario Rosenstock and him are both great :) How about everyone just appreciates both of them

Top class comedian!

Monaghan Legend :)

Never has been an excellent impressionist

his brian cowen is hilarious!

hes dam good, bit of a try hard but we'll get over that........mario rosenstock is more for older people and hes dying out a bit, saw him in killarney and he was a bit bland

He's a half way decent Mario impersonator.

super mario rosenstock is MUCH MUCH better

No he's not.

good until,his simon cowell impression!

Very good apart from Obama

fuck, tubridy has zero flow!!!

Oliver is way more talented and funnier than Mario Rosenstock, Rosenstock was rubbish on the recent late late show....

Not too bad at the accents to be fair. But his material is awful. He really needs someone to write for him. His main themes always seem to be similar to the "Carry On" films in the 1960s plenty of innuendo. Gets boring after awhile. Nothing witty or new there.

His latest show is about as funny as a boil on my bum
