I just played a TvP where the opponent waltzed a probe past my scouting SCV, past my SCV building a barracks, and nonchalantly into the FoW off in the corner of my base. I send and SCV over there 20 seconds later and sure enough, it's a pylon. I pull SCVs and kill it, then ebay block his natural while going 3 CC. Because he has no gateway, he has to kill the ebay from 25% health with a probe before expanding. And somehow, I still lose. I'm so unbelievably bad.
