My dad watched a lot of Star Trek when my little sister was young. She used to do the Vulcan hand salute and say "Live long in Frostburg!" - Frostburg being the small town where our grandparents lived. It was so cute that no one had the heart to correct her, so it wasn't until she was in her teens that she figured out it was supposed to be "Live long and prosper". She's still a little annoyed at that one!
