Not good enough for me knowing there are Thomas Midgley Juniors out there:
On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of TEL, in which he poured TEL over his hands, placed a bottle of the chemical under his nose, and inhaled its vapor for sixty seconds, declaring that he could do this every day without succumbing to any problems. [...] Midgley later took a leave of absence from work after being diagnosed with lead poisoning.

He was the jackass who invented both leaded gasoline and CFCs and inflicted them on the world.
