Bleacher Report found itself in hot water with Dallas Mavericks owner and Shark Tank personality Mark Cuban over a tweet they sent out this past Saturday.

The infamous tweet read DIRK FOREVER and featured a gif of Mavs player Dirk Nowitzki throwing up an air ball. This prompted Cuban to send a profanity-laced email straight to the President of Bleacher Report’s parent company Turner, David Levy.

“Who the [expletive] thinks this is remotely acceptable and why are they working for you David?” wrote an irate Cuban. Levy responded, saying that it was just a joke aimed at “millennials”, prompting Cuban to threaten to “communicate with the millennials in the way i know how”.

Cuban then tweeted out the email conversation to his followers, deleting it when BR finally deleted their Dirk tweet. They have since tweeted an apology.

Hello there!

My name is Lucas Marvin, and I am a Junior studying Advertising. I am from Palatine, IL, which is a northwest suburb of Chicago.

On campus, I am a member of Alpha Chi Rho fraternity, AAF, and PRSSA. In my free time, I love listening to music and watching old movies. I even recently bought a VCR and some tapes to really get the true old movie experience.

I’m taking Journalism 200 to fulfill a requirement for the PR Minor. So far I am really enjoying the class. The other classes I am taking this semester are ADV 283, ADV 284, ADV 350, PS 280, and hopefully MDIA 390. This is easily my busiest semester I’ve ever had, but I think it is also kind of exciting.

I look forward to meeting and working with all of you.
