Guys, this is really much to do about a very small problem. If you will get a bit more fiber in your diet which is a good idea anyway, most of the problem with skid marks will be taken care of. For the occasional times you over do on the diet and get a bit of marking, a quick brushing will take care of it. A brush in a decorative contain beside the toilet is pretty common in most bathrooms and certainly is not as offensive as a plunger. I believe I mentioned in an earlier response that I have had good success with just dropping 3 or 4 facial tissues in the bowl and flushing them.
