This did not end up in the ER but is a bit of a funny tale. When I was very young I got bit by a gerbil on my finger but it must of hit something somewhat significant as the blood was spurting. I wrapped a kitchen towel around it and wen to my brother who upon seeing the kitchen towel wrapped around my finger and hand for what I explained was a gerbil bite immediately started making fun of me. Oh did you get mauled by the mighty gerbil or such. Anyway he then unwound the towel and was like. holy shit. and wrapped it back up. He got it tightly wrapped with a real bandage and gauze and such that it slowed the bleeding down so that after a few hours and a rewrap it was no bleeding passed the bandage anymore.
