Mario Rosenstock has revealed he is worried about what Roy Keane thinks about his impressions of the former Man United star.
The comedian appeared on the RTE Late Late Show and left Ryan Tubridy in stitches with many impressions including George Lee and Pat Kenny.
He began his interview by doing his take of Roy Keane, telling Tubs: "Never get sick of doing Roy Keane. I'm just worried how terrified he might be at home watching me."
Breaking out the Cork accent, Rosenstock said: 'If ever I meet this fella I'm going to rip his f*****g head off'
"So I am terrified of that.
"He's like a cross between Keyser Söze and the tooth fairy."
The comedian also questioned how the pundit can appear on tv a day apart and appear to grow a full beard.
He added: "How did he grow a full beard overnight? Are there two Roy Keane's?"
He went on to describe Davy Fitzgerald as "Roy Keane with a hurley".
