how does tom embarrass himself at sunday school in front of becky?

That day in church, the visiting family of Judge Thatcher is given the highest seat of honor. Tom immediately begins to "show off" by acting up because the Judge's daughter is none other than the little girl he is in love with. In an effort to gain even more glory and attention, Tom has finally traded for enough tickets to receive a Bible. But after receiving the Bible, the Judge asks Tom what the names of the first two disciples were, and he incorrectly answers "David and Goliath."
