Haway Five O

Alright, so basically, there's this TV show called "Hawaii Five-O," see? But this joke is twisting it up by using "Haway," which sounds like "Hawaii" but is Geordie slang for "Come on." It's funny 'cause you're probably too thick to know Geordie is a dialect from Newcastle in England. Bet you didn't know the Angel of the North is there, ya dafty!
