Well, if the surface is perfectly flat and frictionless then you will just
move the clothing one way and yourself the other, then when you pick up the
clothing and move it in front of you again you will move yourself back to
your starting point. Nothing gained. Your mistake was in getting mixed up
between theoretical ice and real ice. :-)

To the optimist, the glass is half full.
To the pessimist, the glass is half empty.
To the engineer, the glass is twice as big as it needs to be.
