Reminds me of what happened a while back when I was growing up in the COng. A friends dad always used to ask them on the ride home what the talk was about. On this Sunday the CO gave the talk and he used the line "bet you can't eat just one" from the Lays Potato Chip commercial, which used to get lots of airtime in the late 60's, when her dad got to her little brother, he said he remembered what the talk was about - potato chips.
Some of the adults there that Sunday probably didn't remember too much more than that line themselves.
