Okay I bet you thought you would never hear about another person doing what you did, but I'm ashamed to say that I've done that (haha). My immediate reaction was to pull it out of my big toe and it bled like crazy. If you pull back the flap and see yellow then you need to go to the ER and get stitches. Have someone else clean it with antibacterial soap (diluted in a bowl of water of coarse) then wrap it with gauze. Do not get the gauze wet...the next day you may have to plastic wrap it to waterproof it.
