1 Minnesota Jones: It wasn't easy going, excavating Troy. The dry soil turned to dust as we dug, almost choking us.

Sadly for period accuracy, the Heimlich manoeuvre was first described in 1974, and there's no way the Joneses in the 1930s could even know that this is a pun*.

In 2006 the Red Cross adopted the more descriptive name of abdominal thrusts to replace the more colourful Heimlich manoeuvre, named after Doctor Henry Heimlich.
