Being filmed in the late 70's early 80's, part of Bill Bixby's wardrobe consisted of bell bottom pants. After he became the Hulk, the pants were shown to be a size or two too small, and ripped down at the calves. In actuality, since the bell bottoms flair out, they would not rip regardless of how big his calves expanded.
When the Hulk breaks through a brick wall, (typically at the end of the show) the clothing that he wears changes between his approach to the wall, and to the view of him running down the alley, and this is repeated in several different episodes, which clearly looks like the same stock footage being re-used.
In Death in the family when the hulk is fighting the bear some of the green makeup gets on the bear in a few shots.
There are times during the transformation sequences that you can see that the stunt man, who is portraying Banner in mid transformation, is pulling on the sleeves to make the back of the shirt tear. There are also times in which the shirt is being torn upward, and it's clear that someone off camera is tearing it.
Banner's problem is compounded severely throughout the course of the series in that not only is he the Hulk, but people either know he's the Hulk or know he has some connection to the Hulk. He departs them at the end of each episode with unspoken trust that they won't say anything.
Normally in super hero movies, there is the occasional episode where someone finds out the protagonist's secret identity and the central story revolves around him/her trying to cover it up.

There is one little contemplated item that is never explained about David's transformation into the Hulk: his waistline measurements never change. The waistband of his pants never tears apart, even though his growing body rips out of his shirts, his pants legs tear open from his thickening leg dimensions, and his shoes/boots tear apart from his growing feet. Obviously his skeleton grows much larger during the metamorphosis. He grows taller, his shoulders grow much wider, his feet grow longer, and he gains considerable muscle mass, yet the only noticeable change to his waistline is that his pants inevitably pop open and the zipper barely unzips. For the Hulk to wear the same size pants as David, his hips apparently never get any larger.
McGee's frustration at never getting a clear or close up look at " The Mystery Man " (Banner), could be rectified by simply having a sketch artist do a composite drawing of him based on any eyewitness's description of David. McGee would likely recognize him from the drawings sooner or later.
