  • Jamieb, do you like pineapple? We really can't tell. ;-)

  • Pineapple from Thailand (and probably most other tropical countries) is much sweeter and tastier than the stuff they float by boat to more temperate climes. If you don't like pineapple, try it one more time the first time you go to a tropical place. You will change your mind.
