Super glue, I went to the doctor about two years ago. Because I had a 'boo-boo' they used a 'sterile' super glue to hold the sizeable chunk of flesh that was just barely hanging on instead of stitches. Since then I have used regular super glue and it works fine. I'm not a doctor so I don't know the risk of using 'non-sterile' super glue but it works for me...
