It was the same ref calling on Gip each time too, and at one point (after #2 I believe) he looked ready to tee Gip up for arguing the call. The ref looked super annoyed/pissed at Gip at that point, and proceeded to call all three remaining fouls on him over the course of the evening.
Not sure if there's history there beyond tonight, but it was definitely a storyline for this one game.
