Australian Holiday in the UK

Listen here, you knucklehead. You're the kind of guy that thinks a participation trophy is an accomplishment. Let me break down this joke for ya. The joke plays on the stereotype of Australians as criminals and the common phrase "returning to the scene of the crime". It makes it seem like an Australian going to the UK is like a criminal going back to the place they committed a crime. It's funny because it's an absurd comparison and uses wordplay.
