Some people seem to think that milk/ice/soysauce/whatever adds to the clouds/smoothness/thickness/whatever but really all you're doing is making a mess of your pipe and diminishing the flavor.
Coyotero is just kidding around, soy sauce makes for a super smooth smoke, and clouds atleast double in size. Flavor is also intensified greatly, I haven't smoke without kikoman for about a month now. It also cleans your pipe due to acidity.
