Here's an old one, but one of my favorites -- trade with Cerulean.

Man, I haven't been to a convenience store in ages. Sometimes, I miss the sting of flatly-carbonized, over-syruped fountain pop, made from a suicide mix of different flavors. But it's okay, cuz you make it healthy by putting in the pink lemonade Hi-C. That puts vitamins in it, so it's good for you.
