Mine probably involves dog poop on my boot from the Lake Paradise Dog park which must have traveled with me through the Villages Vet's office where I had taken Sport for some check-up, then to Pet Co or perhaps Pet Smart was open by then. I kept on wondering what that bad smell was but never looked at my winter boots for the culprit.
I have others that involve human poop but

happens is all I have to say about that. I did have to throw away some nice tennis shoes of mine because of that misfortune. This was while walking Sport late at night but he was not the one who really had to go. Thankfully, the trash was already out so I just had to strip a little bit and throw it in that Thursday night. No streaking arrest. Now, that really would have been embarrassing.
