Gig 'em

At a yell practice before the 1930 TCU game, A&M board of regent Pinky Downs '06 shouted, "What are we going to do to those Horned Frogs?" His muse did not fail him as he improvised, borrowing a term from frog hunting.  "Gig 'em, Aggies!" he said as he made a fist with his thumb extended straight up. And with that the first hand sign in the Southwest Conference came into being.
