The Carl's Jr. feed started tweeting at 1:30 a.m. Monday, saying it would tweet a new idea every hour of what it could accomplish under Amazon.
Examples include a "Self-driving Restaurant," "Space shakes," a "Cloud-Based Restaurant," and "Carl's Foods Markets" that would be "conveniently located between the kale chips & juice bar!"
The tweets seem to be poking fun at the media hype surrounding Amazon's acquisition of Whole Foods.
But Carl's Jr.'s daylong tweetstorm is striking some Twitter users as a little sad. Replies to the many tweets stretch from confusion and bafflement to outright anger.
The joke reveals a sobering truth of how big Amazon has gotten.
Business Insider's Kate Taylor reported earlier this year that small businesses worried that Amazon would put them out of business.
Investors have even coined a new word, "Amazon'd," to describe Amazon moving into a new business aggressively and sending competitors' stock plummeting.
Carl's Jr.'s satirical tweets are an apt commentary on the reality retailers face in the Amazon era.
