For a moment I thought you would make a dirty joke and started talking about the edgeflow of a turd.aha cool thread.
Yep I have one to tell and its a regular of mine. Whilst sitting on the 'can' I tend to look at the floor tiles and see how they are cut at the corners with strange angles, chances are theres a five sider in there that I want to correct by adding loops to create quaded tiles!! Happens every time!!
