Eminem's artist Boogie shares his Shady sense of humor.

In the just released behind the scenes cut for the Boogie featuring Eminem video "Rainy Days", the two joke about ghostwriting for each other. At least we think they're joking. (Go to the 2:30 mark.)

"Get this album," Eminem said about Boogie's Everything For Sale debut.. "I wrote every single rhyme. I am Boogie's ghostwriter."

Then he clarified that he only wrote the bars that you liked, whereas Boogie wrote the ones that didn't grab you.

"I wrote the Machine Gun Kelly diss," Boogie shot back. "Now what?"

You know what they say about jokes ... Do you think there's anything Shady going on at Shady Records?
