It all started after the DJ called out the rapper for sharing an Twitter photo that showed an open tab for the illegal torrenting website, The Pirate Bay.
"Let's start a Kickstarter to help @kanyewest afford a copy of Serum," Deadmau5 tweeted.
"He needs a small loan of 200$ #prayforyeezy," the 35-year-old artist added.
After the call-out, Kanye responded with many tweets, essentially trolling Deadmau5 for his signature mouse head.
"Whose job is it to carry the head on the plane," Kanye wrote. "Do you check the mickey mouse head or carry on? Does it get hot?"
"Is there a portable fan situation?" the rapper continued. "When you get married will your wife have a giant minnie mouse head? # This brightened up my day… thank you dead-mow-five."
Then Kanye inquired about Deadmau5 performing at his daughter North's birthday party. (As Minnie Mouse, 'cause she prefers it.)
"I need you to perform at her party with specifically a minnie mouse dead-mow-five head… not a mickey mouse dead-mow-five head," he added. "I’m very detailed oriented and I will know the difference so don’t try to just throw a bow on the original head…"
"I want to stream you performing in a Minnie Mouse head on @TIDALHiFi," Kanye concluded his tweetstorm.

Was Kanye illegally downloading music? Will Deadmau5 take him up on the birthday party gig?
Only one thing is for certain -- in moments like this, you have to wonder if Kris Jenner really will try to "ground" her son-in-law like she joked she would.
