Over the past year I have found some pretty weird stuff on well travelled routes.
A deer foot, taxidermy not road kill, now a coat hook, don't know how it got there
A heap of hardcore porn DVD cases, empty and relocated to the nearest garbage can on my route.
Money, I found $147 bucks blowing around on the road, felt pleased with my sudden windfall until a little further up the road was a wallet, credit and cards and license spilling over the road, returned to owner.
Money, the odd floating bill, the best being a $20.
Tools, best a three foot Snap On pry bar.
Toyota Camry keys on the local bike path, several trips up and down asking people if they had lost their keys found the owner.
I am always looking for road kill for my other hobbies but don't think it counts as weird ride finds, maybe just weird rider.

all the stopping makes for a terrible average speed, that's my excuse anyway

What have you found?
