The comedian - who has two children of his own, aged 15 and 11- admitted that writing and performing the show has had a cathartic effect and made him more sympathetic to his parents.
"Time goes on, and with time comes understanding," he said. "I think the show is about love on some levels.
"There's no question that doing the show has revealed something to me," he added. "I am a combination of my mother, who always desperately wanted to tell people her feelings, and my dad, who was very sweary and a very male kind of bloke but always wanted to get laughs. That combination makes for a comedian."
