Not a burger as such, but a place near me did a burger which was aptly nicknamed the "heart buster".
It consisted off a bin lid sized barm, with 4 sausages, about 5-6 pieces of bacon, scrambled egg, fried mushroom, grilled tomato, 2 x hash browns.
I made my own burgers once.
Burger meat, some nice cheese.
Made two thin burgers, placed a round disc of cheese and put the two burgers around it like a pouch. Fry that, some lettuce, some 'Taste the difference' tomato chutney, and 'Taste the difference' ciabatta buns.
Nothing better than biting into the burger and the cheese melting out like when you break open a fried egg.
Great burger.
Why the ketchup hate?!
