I do not have fingers, but I have a ring.
Dogs bark when they hear me ding.
I introduce visitors, though not by their names.
Naughty little children push me in their games.
What am I?
Our dinner guests howl that we're evil
When they notice their place in the meal.
But it's no big deal why;
We're just one happy tribe,
And we get really fed up with people!
Who, or what, are we?
