The world of TV sitcoms has seen its fair share of awful, gross and debaucherous people, but many of them pale in comparison to the force that is Frank Reynolds. The patriarch of the Always Sunny family and lead owner of Paddy's Pub is the kind of character you love to watch but would prefer never to meet in real life.
Introducing Danny DeVito to It's Always Sunny in Philadelphia was the spark the show needed to turn itself into a classic. Now, close to two decades later, it's one of the biggest sitcoms of all time, with the latest season (lucky number 15) being yet another fun instalment of the show. Without the introduction of Frank, the series might never have come this far.
So, with 14 seasons under his belt, you've got to believe that this ruthless money man has generated plenty of facts and trivia, and you'd be right. There's a tonne to learn about Frank from his almost entirely bald head down to his toe knife, but how much do you really remember?
See if you can get 100% and if you do, and then treat yourself to some rum ham!
