what is the worst smell you have ever smelled

The bathroom just after my wife has been in there.

When the stomach and intestinal track of a dead body was cut out and dissected. Followed closely by a dead body that has bloated in the sun or water for a week..

Some of the pot these fools smoke. All grown inside, houses covered in Black Mold, smoke up Johnny.

evidence collected from a decomposed body

Rotting potatoes, which can also kill!

A dead chick found in an egg.

Decaying flesh.

Skunks ! Yukkie:-(

Maggots on dead meat

Rotting deer or my mum accidentally reheating a pork chop in the microwave for half an hour... black goo and gross scent that didn't leave the house for a few days.
