Our Valued Customers is a webcomic run by cartoonist MRTIM, who works in a comic book store. MRTIM assiduously records the strange conversations he overhears in his shop for posterity's sake. The result is nothing short of amazing.
Says the site's founder:
This site depicts REAL things said to me (or at least near me) by customers in the comic book shop that I work in. These are real people. This is what they look like and this is something that they actually said.
My favorite strips are those in which customers postulate which superheroes could kill other superheroes (and there are a lot of them). You can read 200+ of these gems at the main site.
