Chewy Popcorn Balls

1 bag marshmallows
1 stick butter or margarine
6 bags microwave corn (unbuttered)

Pop the corn and let cool. Cook marshmallows and butter in a saucepan over low heat until syrupy.

Using contents of 2 bags of popcorn at a time in a very large bowl, pour 1/3 of mixture over popcorn and stir until very sticky (may have to reheat).

Butter hands before forming popcorn into balls.
