We're back with another 5-day trivia hunt!

Again, the rules: Every remaining day this week, I'll be presenting a specific challenge. Your job: come up with the answers and hold onto them! Why? Because on Monday, next week, you'll need them to solve a short puzzle. The first person to email in the correct answers and successfully show how you arrived at them (thus the title: How Did You Know?) wins a choice of any TWO t-shirts and book from our store. We're also doing something new from now on: in addition to the above, we'll be awarding a t-shirt to one random winner who has all the correct answers. So even if you're not the first one with the right answers, there's still a chance to wind up a winner on HDYK?

And remember, we're also giving away a really big, sa-weeet prize to any winning contestant who can defend the title three months in a row. Nathan Richards is our current champion.You can read about him here.

As with previous How Did You Know? posts, comments have been turned off, but I definitely encourage you to work in teams like our present champions did. Write your friends, send around each daily challenge, conspire, work together, whatever it takes to make sure you're armed with the right answers going into next Monday's puzzle.

Today we're playing Name That TV Theme Song. On the next pages, you'll find 7 tunes. Your job: I.D. the shows that used each tune as a theme song.

See you back for your third challenge tomorrow...
