Due to a (very) minor snafu at my wedding on Sunday, I find myself in a position requiring me to mail out a hundred CDs to my wedding guests (one per family, or thereabouts). In my online search for the cost of a padded envelope, I came across the Postal Service "District Sleeps Alone Tonight" single for sale via the USPS online store.
Thought that was weird, until I realized that it was brilliant.
