An old interview with the actor has recently gone viral.
And a recent clip unearthed by one Twitter user shows what happens when you try to prod Hill about his physique.
In a 2014 interview following a period of substantial weight loss, when Hill was asked whether or not he was still perceived as the "fat guy" at Hollywood parties, he quickly dismissed the question altogether.

"Do you have any other questions, that are smart?" Hill shot back.
Since then, Hill's weight has appeared to fluctuate with some regularity, a trend which may not be doing his heart any favors. One study, published in the International Journal of Obesity, shows that "yo-yo dieting," or repeated dramatic changes in weight, is a risk factor for cardiovascular disease later in life.
But, as of late, Hill has appeared to find an exercise regimen that consistently works for his body.
In January of this year, Hill unveiled a trimmer version of himself and has managed to keep those pounds off.
In a March interview, the actor attributed his success to a better diet and has only looked fitter and fitter since.
