Adam is in a panic, Eve is having her first Period!
He Prays to God:
Adam: God, Eve is bleeding between her legs. I don't know what to do!
God: Don't worry Adam...it's nature. What have you done so far?
Adam: I took her down to the river to clean up...
God: I wish you hadn't done that
Adam: Why not?
God: I can get the blood out of the river, but I'll never get the smell out of the fish!
