I actually liked the original title to this thread, as when I first read it, I thought that it asked if Gandalf would ever
eat hobbits, which I thought had some support, as Gandalf had no problem egging on Bert, Tom and Bill with cannibal culinary advice. I also thought the thread title could be mischievously misinterpretted to mean that Gandalf could beat them in basketball.
That said, in regards to Gandalf physically disciplining the hobbits, we find no evidence in the text that he would so such a thing. He just barks a lot, unless it's orcs or other beasties, then he kills them. No cudgeling some errant orc - swoop, and off with its head.
Peter Jackson and his crew, on the other hand, found ample evidence of Gandalf physically disciplining hobbits, yanking Pippin's and Merry's ears, dragging poor Sam through the window (and using the word "verge"

). He later takes to smacking royalty, finding that just as entertaining (i.e. Theoden the Possessed, and Denethor the Flaming).
So, again in answer, 'No.'
