Late Late Show viewers not happy
Late Late Show viewers were less than impressed with RTE's decision to wheel out Architect Dermot Bannon for another appearance.
Dermot joined host Ryan Tubridy to discuss his love life, and even revealed that he was once a contestant on the legendary Blind Date show as a young man.
Not everyone was happy to see the Room to Improve presenter on the programme, with many commenting on the frequency of his appearances on the Late Late.
One person joked: "Ryan Tubridy at 8:30pm going down to release Dermot Bannon from the RTE Basement."
A second said: "We are only 2 months into 2022 and Dermot Bannon already has TWO #latelate appearances.. #latelateshow."
