This is a prime example of why it is a bad idea to ask a comedian to "tweet about popular brands." Some language is NSFW.
Friday afternoon, a company called Brander solicited comedian Patton Oswalt via Twitter to ask him to tweet about products they represent, and Oswalt ended up having a lot of fun with it. He went on a tear making fun of the company and their strategy with a series of tweets that amassed hundreds of retweets and attention from the press.
