True irony comes from a bin of unwanted trucker hats abandoned in a Goodwill store on the backside of Main St. Walla Walla Washington. Here's what it looks like, waiting quietly for local college students and hipster bands rolling through town.
Note: for European reader the trucker hat reference may not cross the pond. Maybe an equal corollary would be a bin of Royal Post caps in the Oxfam shop around the corner from a small town's main square. Still not following me, then this street guide to irony will help.
