If the list has only two items, do not use a comma.
For example: Rick and Steve made a snowman.
If the list has more than two items, use commas between each item, but not after the last item.
For example: Rick, Steve, and George made a snowman.
If you are joining two sentence, you must use a comma before the conjunction.
For example: Rick and Steve made a snowman, and George was jealous.
