OH GOD I WAS CHEWING THE OTHER DAY AND I THINK I GOT A PIECE OF CRACKER STUCK IN MY TEETH AND WHEN I WENT TO BITE DOWN OR SOMETHING IT MADE THIS REALLY LIKE ALMOST METAL SOUNDING NOISE, IT WASN'T PLEASANT AND IT MADE ME FEEL SICK.

but nothing bad happened and soon i brushed and was on my merry way

what's the worse noise you've heard lately?
