Also in the safe is the ring Sheldon was planning to give Amy, which he then shows to everyone.

Bernadette's dad says he knows Howard doesn't want to have kids. Howard is surprised by that statement, telling Bernadette's dad that he would love to have children. It turns out that Bernadette is lying.
