A Missouri kindergartener had a weird offering for show and tell -- he brought his mom's crack pipe and crack!

Students had been told to bring in family photos and family items to share with the class. When it was his turn, the 5-year-old opened his backpack and pulled out a crack pipe and a baggie of crack rocks.

The child's mother was charged with possession of a controlled substance and one count of first-degree child endangerment.

The boy is now being cared for by family members.
