My wife and I are both teachers.
One day she was teaching a kindergarden class and they got onto the topic of the ocean and what lived there.
When she got onto the topic of " an octopus" she asked the students what did they know about "the octopus"
On student said that they have eight legs
another student said that they had Tentacles
A third kid jumped up and said that he to had tentacles. Another observant kid said where are your tentacles? Quick as a flash he dropped his pants and pointed downstairs and says " here are my tentacles, but I only have two"
No bullshit, fair dinkum story that actually happened.
We laugh frequently about that one.
