The Worst People You Know

This is the thread where you mention that one person (or person's) (<------ Not a word)
that piss you off more than anything alive (or dead) and why.
For me, its my old Geo teacher, she was a fat hippo and probably one of the most evil creatures on gods green earth, if there were any justice, she would be killed. (played favorites, had no idea what she was doing, generally mentally challenged (like most swedish teachers) and all around cruel to the students and abusing her power) She would actually enjoy forcing everyone in the class to take off their sweaters and jackets ''because its not appropriate indoors'' and then put on her own and open all of the giant windows that existed in each classroom, and this was during winter when it was -20 degrees outside.
With Fire.
Lots of it.
And really, by some miracle of nature: the fire itself should also be on fire.
