Four Wings Around

I have four wings, but cannot fly, I never laugh and never cry; On the same spot I’m always found, toiling away with little sound. What am I?

Not Your Brother

You give someone a dollar. You are this person’s brother, but the person is not your brother. How can that be?

Bring My Victims Together

The things I bite, they don’t bleed,

I don’t bite until you push me;

I bring my victims together each time I bite,

But they’ll come undone if you pull it just right.

What am I?
