What is the chemical compound with the worst odor you can think of?

I want to prank some friends with something really fucking foul, my first thought was Amines since they are somewhat easy to produce, specifically Cadaverine and Putrescine.

I have heard of many other compounds that smell like literal death such as Thioacetone and Selenophenol but i cant find a way to synthesize them without wasting 4 months of my life and a ton of fucking money.

Any chemist have suggestions?
