Answer:
Some are clean and some are dirty, but all are meant to get a chuckle. Most like it, some takes offense from it.
I am the black cloak of the road
What has a throne, but has no king?
What do you call a classy fish?
Has a tongue, but never talks. Has no legs, but sometimes walks.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
