My first day on the job went well. It appears that engineering is a universal trait, in that my fellow engineers seemed less Aussie than Engineer, so we spoke a common language, despite the inability to specify certain food groups (i.e. biscuits).
I did get a lot of laughs with my Dumb American jokes. Fortunately, that is an inexhaustible resource. They agreed with me that Australia does not actually have politics, at least in the American psycho-circus infotainment sense of the word.
