A man once tried to check his car's fuel tank at a petrol station by lighting a match, luckily the pump attendant yelled at him not to do so.
:D
Ignorance is not always bliss, I myself have done stupid acts, like as a kid, I once threw water on an electrical wire that caught fire. My father corrected my science sense after that. But still, acts of stupidity are sometimes done in ignorance. May God keep everyone safe.
