Nob Nation (Gaa Special Late Late Show)Funny 

Brilliant, just brilliant. I don't live too far from him actually. Oliver, you did us proud, well done! Love your take on Willie O'Dee, class.

Love Oliver Callan! He is brilliant!

fantastic stuff, his scripts are absolutely hilarious. I love him doing David Norris, it cracks me up. Wonderful satire.

Brilliant 👏

he is seriously brilliant

his Mícheál Ó Muircheartaigh is spot on!

His Enda Kenny is absolute spot on, as is his Mícheál Ó Muircheartaigh!

michael o muireaheirtach (or however ya spell it) is class

he is great he is near as good as mario

Absolute spoon!

His biffo impression is classic

very funny

I still stick with what I say. You only realise how good Mario Rosenstock is as a writer when you watch this or listen to Nob Nation. He really needs a writer. But he is a talented mimic.

olly callan is a legend!!! nob nation is so much better than gift grub

Best bit is at 2.12. Who is she?

Fantastic impressionist! Very underrated

HARVEY WEINSTEIN in the Thumbnail

no we pay for every channel bbc one itv rte and all that jazz

you're dead right! Brian Cowen rarely misses a Sunday match down here in Offaly!

He was right about mayo but dead wrong about the dubs

Brian CowAn is spelt like CowEn! I don't think that Bertie Ahern is much a GAA man either!!

i agree but imitation is the highest form of flattery.

hey any1 on facebook? look up ...How can Brian Cowen be Taoiseach when he's at McDonald's the Whole time ... and like the page thanks!! LOL

wow that was a bit of a lead balloon! Bit OTT I thought especially the cheap shots at Norris

but he's far more talented than mario. And im saying that as a giftgrub fan

@geraldog21 This guy is way better! Mario doesn't even sound like the person he does

@traber89 What would I know about it?? everybody knows a good impressionist when they see one and Mario Rosenstock is SHIT! I speck for the country when saying it's quite hard to figure out what celebrity he's doing as for Oliver Callen, you know straight away

im not a fan of cowen but he is as much a gaa man as ahern is

That was awkward

He lost the crowd when he made fun of the legend dat is Ciaran Mcdonald.

why is this funny , one star is an insult

stupid for a GAA specific Late Late Show - too general. David Norris? Brian Cowan?? are they known as GAA people? granted he had to stretch for 10 mins but still too general

I generally hate impersonaters. Hes one of the most anoying ive seen

Embarrassing

Bellend!

The voices are good. The material is terrible.

MARIO IS BETTER

Clown

not great...fairly shite actually! Mario is best!!

rubbish

Rubbish

he isnt half as gud as mario rosenstock,just a cheap imitation

He does good impressions but in my opinion the comedic content is weak,very weak.
