How Did You Know? [Day 2]

To recap, every day this week, I'm presenting a specific challenge. Your job: come up with the answers and hold onto them! Why? Because on Friday, you'll need those answers 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 t-shirt or book from our store.

In case you missed Day 1 of this feature, check out yesterday's challenge here.

Today, after the jump, you'll be asked to solve a riddle. As with yesterday's challenge, I definitely encourage you to work in teams. Email 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 Friday's puzzle.

Now on with the hunt!

In the following riddle, I'm looking for three words that are related to one another in a specific context.
