I've been watching This Old House on PBS for a number of years now. When the show starts, they have previews of that days episode and then they have a few sponsor advertisements before the programs real content begins.
There has been a GMC ad that has been going on now for far too long. There are three men at a construction site attempting to move a bolder by their hands and a few simple tools. They express how difficult it is and then off handedly say that they need elbow grease. Just then, a GMC van backs up and it has barrels of elbow grease. The timing of the arrival is perfect.
The ad is suppose to be mildly funny. But GMC needs to come up with a new one. It has been around far too long.
