Fred Cooke did a spectacular job for RTÉ of mortifying this girl in Dublin’s Powerscourt Centre.
After the comedian has settled into a seat next to the girl and her friend in a café he decided to ask her out for dinner.
Thinking he was just some random guy she dismissed his advances.
"I'm meeting my boyfriend later," she said.
Hoping that would be the end of it the girl resumed conversation with her friend.
Fred Cooke was not taking no for an answer however, particularly because she was the pawn in a flashmob style scene from 'My Best Friend's Wedding' for RTE.
Shortly after breaking into song and being joined by a choir, he revealed his true purpose.
She was, needless to say, mortified.
