Americium was discovered by Americans! (the plot thickens) It's radioactive and in smoke detectors so don't eat your smoke detector unless you want to turn into a multistory lizard like creature.
Element 95, after Plutonium and before Curium. No, there is no Canadium or Mexicium. Not even a freakin' Germanium (oh wait...) But no Australium dude! If I discover an element I will name it Australium, that'll give them Americans with their "Americium" what for!
It's not even pronounced like America, it's pronounced A-mer-e-sea-um. WHAT ARE THEY SMOKING???
