I recently lost a thumb while I was trying to help some guy out with his tv. I have kept the thumb in a jar of pickle juice, is there still a way to re-attach the digit even though it has been 48 hours?

Laceration in Lancaster, There is no need to re-attach your thumb. Most people don't even use their thumbs, they are mainly just there for show. My advice would be to tape an aspirin to the bloody-nub and get back to repairing that tv. The show, or in this case the repair of the device that broadcasts the show, must go on.
