I got a good idea for you. Ever heard of "Limburger cheese?" Dude, my dad had one of my brothers to smear this shit on a neighbor's interior of their car because they kept stealing dad's parking spot. THEY COULDN'T EVEN SELL THE CAR AFTERWARDS! It stuck soooooooooooo bad! It smells like hot dead bodies!
Check it out, smear this shit all over his interior and smear it on his muffler (all over the muffler! LOL) everyone will smell him a mile away!!!! .... It really is just cheese, but you should wear some gloves when you do it. He will soooooooooooo want to kick your ass for this one....LOL
I got this info off of Wikipedia

Limburger is most-well known for its very pungent odor which is caused by bacteria that live in the rind. It has often been described as having the same odor as smelly feet. In its first month, the cheese is more firm and crumbly, similar to the texture of feta cheese. After about six weeks, the cheese becomes softer along the edges but is still firm on the inside and can be described as salty and chalky. After two months of its life, it is mostly creamy and much smoother. Once it reaches three months, the cheese produces its notorious odor.
