Name any two pranks by Tom Sawyer?

1) Tom tricks other boys into whitewashing the fence for him by pretending the chore is actually quite enjoyable. He even gets paid (in trade) for allowing some of the boys the honor.

2) Tom trades for tickets in order to gather the number needed to trade them for a Bible. Tickets are earned by memorizing Bible verses. Tom, however, doesn't really want the Bible, he merely wants the accolades that will come with the accomplishment. Unfortunately, it wasn't his accomplishment.
