Octopus Tentatacles

So I forgot to add this with my last post. I went to an elementary school yesterday to assess a child's reading level. The student is asked to read a passage at their instructional level, then we ask him questions afterwards to see how much of the story he understood and how much he can remember. On our drive back to BYU, a girl in my class told of how the girl she was assessing was asked to read a passage on Octupuses. One of the comprehension questions at the end of the passage was "How does an octupus move?" to which the shy girl quietly replied "the octopus moves by his testicles". She said she had a hard time keeping a straight face after that and the girl continued to call them testicles instead of tentacles. I just thought that was a funny story...that poor girl is going to go home to her parents and tell them what she learned in school! The girl that is in my class never corrected her so who knows how long she'll go without knowing the proper term!
