Bark

Today, a little joke with homonyms… We should have plenty of humour in our classes.

 An English teacher enters to his class. He wants to revise the vocabulary they have already learnt about plants, so he starts asking his students.
- What is the name of the green parts of a plant? – he asks to one of his students.
- Leaves.
- Good. And you, Peter, what’s the name of the outer part of a tree?
- I don’t remember teacher.
- Bark, Peter, bark….- he reminds to his student.
 - Woof! Woof!
