Why do giraffes have long necks ?
Because their feet smell.
My son (so not a joke) was asking me why his primary school teacher marked the following questions as wrong:
Question 1: Write a sentence using "understandable"
His Answer 1: Write a sentence using "understandable"
Question 2: Can you write a sentence using "corrupt"
His Answer 2: Yes.
I'm so proud (but he didn't get any marks).
