The radar level was tied off for mast stepping, should we untie it? Naw, got to go up on the chair anyway to hook up the lazyjacks.... except... the line is tying off the halyard too, can't use it to go up. But, I noticed that it is all tied off with a slip knot. All I have to do is grab the end and pull....

'Course I suppose everyone has done this at one time or another.
