If you lick your envelopes... You won't anymore!!!!!
A woman was working in a post office in California, one day she licked the envelopes and postage stamps instead of using a sponge. That very day the ladycut her tongue on the envelope.
A week later, she noticed an abnormal swelling of her tongue. She went to the doctor, and they found nothing wrong. Her tongue was not sore or anything.
A couple of days later, her tongue started to swell more, and it began to get really sore, so sore, that she could not eat. She went back to the hospital, and demanded something be done. The doctor, took an x-ray of her tongue, and noticed a lump. He prepared her for minor surgery.
When the doctor cut her tongue open, a live roach crawled out. There were roach eggs on the seal of the envelope. The egg was able to hatch inside of her tongue, because of her saliva. It was warm and moist...
This is a true story...
