You speak of sleazy, underhanded professions?

How about diplomats?

Diplomats lie quite well, the cheat foreign diplomats and rulers, they use underhanded tactics, and if they hadn't cheated and sleazed correctly against the "Evil Empire", neither you nor I nor anybody in the US and Russia would be alive. Instead, the whole world would be saturated with some unusual, decaying transuranium radioisotopes, which had already killed all of us and were working on making the planet into a brown/blue rock.
