In RSE, I learned that Gabby and Ty have a special dialogue entry if you throw a Poke Ball at them during their battle. They call you out on it after the battle and again during their TV segment. This doesn't happen in ORAS, though.
(I didn't personally do this; but throwing a Poke Ball does have a niche use as a way to skip a turn without wasting a Power Point or switching Pokemon, mostly against Dig/Fly/Dive users. Poke Balls are the cheapest consumable item that don't require a specific status condition to use in Gen 1/2/3, and you don't waste them in Gen 4+ by using them to skip your turn.)
