If you don't mention this epic radio phone call on Father's Day, are you even celebrating Father's Day?
We think not.
The infamous phone call happened more than 10 years ago but it still does the rounds on social media every year around this time.
The clip is originally from More FM's "Reverse Trial" show, when host Gareth Lischner tried for nearly two minutes to get caller Solly to say the question which was, in fact, the answer: "What day is Father's Day?"
