RTE viewers were left asking the same baffling question after an explosive documentary about the Saipan fall out aired.
Roy Keane left on the eve of the 2002 World Cup after a fall out with manager Mick McCarthy.
The feature length documentary aired as they took a deep dive into the infamous walk out 20 years ago.
And as the World Cup started, RTE took a deep dive and had a number of famous faces involved.
Former Taoiseach Bertie Aherne, World Cup participants Ian Harte and Jason McAteer were among the contributors.
And so too was comedian Mario Rosenstock which left viewers confused.
One viewer said: "Why is Mario Rosenstock in the Saipan documentary."
While another said: "Hopefully with this one Mario Rosenstock really lifts the lid where the other 1,000 documentaries haven’t"
And another said: "Burning question raised by this documentary...what is Rosenstock doing on it."
