Glad you asked! There's a story behind it. I once tried to catch a mouse and all I got was this pair of dirty socks. I know, it's anti-climactic but the way it happened was funny. I've been hunting this creature for days with no success, traps set everywhere, including a dirty clothes cabinet. At some point I forgot where I set the traps, the rat outsmarted me. I gave up once I threw my socks down the dirty clothes bin. The mouse/rat was eating my clothes and I thought that would be a perfect placement. Alas...
