Clean, fun jokes... the tradition continues

I was teaching a young colleague how to replace the ionisation filament in our mass spectrometer one day. i asked him to undo the bolts on the flange. He immediately grabbed a 10" shift spanner. i stopped him, explained it was a German manufactured machine and he'd need a 250mm metric shift spanner. He dutifully started looking for one. I then let him in on the joke and explained that in fact, I stopped him because I didn't want him to burr all my flange bolts with a shift spanner and that he needed to use an offset 13mm ring spanner.

For the pictures with the two cars, is it that they rhyme? Gran Torino, El camino?

The flames are painted on backwards because the Pinto gas tank sometimes exploded on impact in a crash.

As "an older guy," I think the first one is funny (but sad, too) due to the association of the Ford Pinto and its unfortunate tendency toward catching fire if struck in the rear-end. https://www.motortrend.com/features/ford-pinto/
