2 separate bananas - each with a written address on the peel and postage. Did they NOT expect these to get squashed under the ton of mail during shipping? They did not by some miracle
Fedex/UPS - Everyday I find atleast 6 packages of the wrong carrier in the 60,000 pieces of mail that I handle. It makes me laugh to think that the odd are that there are 1 in 1000 people who do not know the difference between USPS, UPS, and FEDEX.
Fake grenades - one day a box opened us containing a grenade and the building was evacuated while the item was analyzed. Turned out to be a plaque that said "Pull Pin When All Else Fails"
Human Blood, Feces, Body Parts - If not properly wrapped, these items create a real hazard for us employees and we are not allowed to be informed dur to HIPPA laws as to why it was being tested. One of my co-workers was slashed with feces and needed to be tested to EVERYTHING every month for 6 mos then every 3 mos after that.
that is just some stuff thought you would laugh
