As I sit here watching My 3 Sons, having my morning coffee, there was another SR sighting, this one more exciting than other shows.  This show deals with Steve showing Chip what he does for a living as an aeronautical engineer, he goes over to the drafting table, picks up his bamboo SR rule and says

"Do you want to see how a slide rule works?, you do lots of things with it."

 

A TV character that actually knows how a SR works..........what's the world coming to?    lol
