A few ideas:
1. Get modeling clay. Make a figure of a woman and a figure of a man. Coat the woman in salt. Make sure she's looking over her shoulder and the guys is looking at her all sad. Lot and his wife.
2. Modeling clay. Cain and Abel. Lots of fake blood/Abel's brains all over the altar.
3. Adam and Eve in the garden of Eden (modeling clay, of course

). Give Eve really, really big boobs.
4. Noah laying drunk in a tent, naked, and his son is looking at him.
Just pick out random shit and make a clay scene of it.
