I have won against plenty of people with this strat., ok first off get 3 or your SCV's to mine minerals and send one to the enemies base if you know where it is, or to scout, if yuou know where it is attack the main building, the other persons "underlings" should be coming for your SCV, run it around in the map trying for it not to get killed, eventually your oppent will call th other guys off, when they do build bunkers out of your enemies range, and build a barracks in your "base" as well, then send marines in as fast as you can, as soon as you have one marrine, load it in a bunker, and get the SCV you had chased around the map to harass their Pylon/Depot or other building, then lead it to your bunker which should have two maybe three marines in it, and they will kill the enemy drones/SCV/Probes, therefore halting production and an easy win for you.
if you can do it fast enough with zerg, spring board into lurkers, and research burrowing and put 3/4 lurkers right in front of the enemy base, although I never tried it with zerg.
CreepColony's Opinion: This will require a lot of micro, and can be risky.
