The Bird Flanagan was described as a "Playboy" and a "Practical Joker". It was reported that he once "went to a fancy dress ball at the roller skating rink in Earlsfort Terrace wearing wings and a tail and laid a huge egg on the dancing floor" ... this was the origin of his nickname.
His father owned a huge thriving market garden business that at its peak took in more than 500 acres of prime land in southwest Dublin, stretching from Tallaght to Rialto.
