As you walk around, you think about how it's summer, and the perfect food for a hot summer's day is a nice, juicy melon. You're not very picky about what kind of melon; you like them all.
As luck would have it, there's a stand of melons available for sale. You push your cart over to inspect them. There are three types available: honeydew, cantaloupe, and watermelon. All three sound amazing. You'd like to get them all, but they're too pricey for that. You'll need to choose only one.
If you had looked at more than just the price on the sign, you'd probably move on to a different fruit, however. The sign mentions that these melons will affect breast growth.
