Watching Irish people eat things has proved entertaining before, but there's now a moral obligation to monitor the situation as the video series taste test American hamburgers.
Your first question should be: Don't they have hamburgers in Ireland?
Yeah. There are hamburgers in Ireland. However, the taste test highlights the compulsion people have to tinker with the most quintessentially American thing in the world (an eagle draped in a flag riding a jet ski made out of apple pie stares wistfully at its second place ribbon).
It takes a handful of Irish people eating five hamburgers to reveal there are more confusing mutations among hamburgers in America than there are in 52 years of X-Men comics. There's a burger for every occasion and tastebud. Vegetarian? Quinoa burger. Hate yourself? Cauliflower burger. Looking for a delicious way to die? Try the donut burger with bacon, which made one taste tester remark, "This is what liberty is about." Yes. Yes it is.
Also, what the other guy said about marijuana being legal in Colorado. That's also what the donut burger is about.
