Never Lick Postage or Envelopes:A girl licked envelopes and postage stamps and cut her tongue. A week later, her tongue was swollen but not sore; a doctor found nothing wrong. A few days later, it swelled more and got so sore that she could not eat. An x-ray showed a lump. The doctor cut her tongue for minor surgery; a live cockroach crawled out! There were cockroach eggs on the seal of the envelope (they eat the glue.)The egg hatched inside her tongue since saliva is warm & moist.
