Riddle: 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?
Riddle: I'm like a doll, But I'm not for playing; I stand up straight, but if windy I may be laying; I'm well-known and famous for having no brain; I work outside both day and night in sunshine or in rain.
What am I?
