What's the best freebie you've ever had?

[bloodiedathame]

Mine has to be some clamps that were left at a house we bough by a previous owner. I've used them to hold a garage door shut, clamp wood to a bench for cutting, hold a shed roof on, used them for hanging stuff on, used them to stop a hastily mounted cabinet from falling down, and probably some other stuff I forget. All for FREE!

Now you go.
