Lost and Found on the MBTA

The MBTA system (Massachusetts Bay Transit Authority) can be a hectic place. During rush hour, riders are crammed in together, buy texting and tweeting, trying not to doze off on the way to and from work. It's understandable that things sometimes get left behind on the trains. One expects the usual; cell phones, wallets, umbrellas, books, but some things that have been found boggle the mind. Example:

Prosthetic limbs
False teeth
African fertility statue

What are some of the strangest, or unusual items have you heard of being left behind on your local bus or train service?

Prosthetic limbs?? How did you loose those? What do you get home and say "Hey wait a minute! Where is my hand??"

Oh waht? And I thought you were for real Diana!

Or even....Oh what? And I thought you were for real Diana!
