Shades of olive drab

This morning I was strolling past a construction site, and much to my amazement all of the construction workers, perhaps thirty or forty, were doing callisthenics. Generally they were in sync with each other. It looked very programmed, as if they knew the routine better than their phone numbers. Some were wisely stretching out, preparing for the days physical labour. The younger ones in the back reminded me of Hawkeye and BJ doing their best impression of callisthenics under Frank and Margaret's heavy glare in that oldish TV sitcom MASH. I could not help but chuckle to myself as I walked by.
