The 25 weirdest burgers ever made

In celebration of Mr Hyde's National Burger Day, when once again the UK will come together to sample only the finest meats and glistening of brioche buns, we thought it wise to list all the times when the world's love for burgers possibly went a bit too far.

And so, from braille buns to exotic animal stuffings, the great to the downright wacky, we've scoured the globe for the burgers you'll struggle to find in your nearest restaurant.

BLACK BUN FRIED FROG BURGER

A limited-edition burger which pops up at Japan's Orbi Yokohama Museum from time to time. Want it? You'd better hop to it.

The Cronut Burger

The donut's cooler cousin, the Cronut, works surprisingly well in burger form. Think a bite to eat for brunch. And you thought your last brioche was sugary.

BRAILLE BURGER

Wimpy actually did this. Remember them? The seeds translated to  '100 per cent Pure Beef Burger Made For You".

QUADRUPPLE BYPASS BURGER

You'll find this artery-clogging burger at the Heart Attack Grill, Las Vegas. Elvis probably died eating something similar.

MARIO MUSHROOM BURGER

1up your friends in the kitchen by getting hold of green food dye, cutting some circles out of cheese and putting this gamer's delight together.

MAC AND CHEESE BURGER

The Mac Attack, all up in your grill. Or rather 'on' your grill?

The 777LBS Burger

A similar sight to how it must look when the paramedics wheel you out of the restaurant after eating one.

Yorkie Pud Burger

Yorkshire-made, 5,000 calories, roast dinner on steroids.

THE RED CHICKEN BURGER

Burger King Japan just gets it.

THE WHOLE DAMN FARM BURGER

Six different types of meat, 6,000 calories, so many reasons to thank Sam Longhurst, head chef of Splendid Kitchen in Manchester behind this dish. Old McDonald has probably bought a yacht.

Spaghetti Burger

Courtesy of Philadelphia's PYT, home of "America's Craaaziest Burgers", you'd probably be shot on site for this in Italy.

DEEP-FRIED PEANUT BUTTER & JAM SANDWICH BURGER

Another one from those madcap Philadelphians - PYT do PBJ

HOT FUDGE SUNDAE BURGER

For the man who wants to get from A to B without having separate plates, an Irish pub in Florida concocted this main course-meets-desert. 

ALPHABET BURGER

Avocado. Bacon. Cheese. Doritos. Egg. Fish sticks. Garlic bread. Ham. Italian sausage patty. Jalapeño peppers. Krispy Kreme doughnut. Lettuce. Macaroni and cheese. Noodles. Onion rings. Pepperoni. Quest blanco dip. Ramen noodles. Spinach. Turkey burger. Usingers bratwurst. Veal. Parmesan. Waffle. Xylocarp (coconut). Yams. Zucchini.

Quite the mouthful.

4LBS BURGER WITH FOUR FRIED EGGS

We're all - ahem - four it.

THE BEER BATTER BURGERNATOR

Never one to waste a drop of ale at Denny's Beer Barrel Pub in Pensylvannia, the 'Burgernator's' meat comes extra crispy and tasting like delicious beer. You'll be back.

The Purple Burger

If you ever find yourself in Baltimore, avoid Natty Boh's beer (it goes down nicely but will make you question your own mortality the following day). Do, however, get yourself down to Kooper's Chowhound Burger Wagon and pray they're serving this purple piece of purple-clad genius.

ALIGATOR BURGER

Big in Florida. They're practically asking customers to say 'make it snappy'.

SOUTHERN COMFORT STUFFED BURGER

When mac and cheese stuffed meat patties aren't enough, add a splash of liquor.

DEEP FRIED DOUBLE TWINKIE BURGER

If cops made burgers, they'd all look like this.

ICE CREAM BURGER

Mr Whippy eat your heart out.

BLACK NINJA BURGER

Clearly not doing its job properly, because we can see it. It's right there!

BACON-WRAPPED PIZZA BURGER

At least it's still in slices, sort of.

WAFFLE BURGER

Suck it, ice cream.

Organic coffee burger

Yes, you read that right. And here's how to make it yourself.
