Sometimes, when you're walking around, you overhear conversations or a comment that makes you chuckle in your head, cringe, bust out laughing, or leave you saying, "WTF?!?"
The online community
Overheard Everywhere allows people to post these quotes, and since then many cities, states, and college campuses have come up with their own versions. Here's Hypography's.
Post the *interesting* things that you hear. Feel free to include time, date, location, circumstances, etc.
