"Why Do?" by Tony

Why do trees have bark?
Because dogs bark
Why do sharks have teeth?
Because they don't live in reefs
Why do fishes breed?
Because the father will lead
Why do animals have scales?
To leave others pale
Why do teachers help?
To make children yelp
Why do humans have two buck tooth?
So people can be smooth
Why do people get sick?
To get others lick
Why do people say hi?
Because others will say bye!
