I will itch it

While working in therapy with a student who was trying and successfully distracted me from getting him to do work:

 

Student asked me: Are you itchy?

Me confused: No
Student: Do you have an itch on your nose?
Me again confused: No
Student: Do you have an itch on your chin?
Me: No
Student: Do you have an itch on your neck?
Me: No
Student: Do you have an itch on your tummy?
Me: No
Student: Do you have an itch on your head?
Me now very curious about what he is getting at decided to change my answer: Yes

 The student grinned from ear to ear and said: I will itch it for you. He then reached over and completed messed up my hair! All I could do was laugh.
