Just started high school chemistry at around 14 years old....Had this 
fungus looking mark about the size of quarter on my arm that none of 
the doctor prescribed ointments could get rid of....Decided to steal 
some HCL from the chemistry lab one day and dabbed some on the spot 
that night....It started burning like hell and large pink craters 
started forming on my skin....Rushed to the bathroom and flooded it 
with water....Well, the good news is that the fungus went away for good 
and the bad news is that I have the scars to this very day.

That episode is in the top five of the dumbest things I ever did as a 
kid.
