Until I was 10, I used to believe that rats has poisonous tails. Somebody told this when I was much younger and I unquestioningly believed it. Eventually, I passed this information on to my friend Roger's younger brother when we were in the nearby ravine. Afterwards, Roger set me right and chewed me out for making it up to scare his brother. I realized how ridiculous it was and was very embarrassed.
