Envelopes and Cockroaches

I'm not sure if the below is true.. but never ever will i use my tongue to wet an envelope.. read on...

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 lady found a cut on her tongue. 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 cockroach crawled out!!!!

There were cockroach 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...

Hey, I used to work in an envelope factory. You wouldn't believe the
things that float around in those gum applicator trays. I haven't
licked
an envelope for years!" I used to work for a print shop 32 years ago
and we were told NEVER to lick the envelopes. I never understood why
until I had to go into storage to pull out 2500 envelopes that were
already
printed and saw several squads of cockroaches roaming around inside a
couple of boxes with eggs everywhere. They eat the glue on the
envelopes.
