A parody coffee shop mocking Starbucks opened this weekend in Los Angeles and is quickly becoming a sensation on social media.

The shop, "Dumb Starbucks," looks nearly identical to the real Starbucks—with the exception of the word "dumb" being prefixed to the title and menu items.

A Starbucks spokesman told the Wall Street Journal that the company has nothing to do with the new shop, but is looking into it.

Dumb Starbucks, which is staffed by two baristas, offered free coffee all weekend. Lines extended out the door.

Amber, one of the baristas, told the Journal that the shop's use of the Starbucks logo for marketing purposes is legal because it's a clear parody.

Diners took to social media to express their fascination and amusement with the new shop.
