With the amount of shit threads in here, this deserved one.

Electronica artist Deadmau5, who performed during the landmark dance-music collaboration with David Guetta, Chris Brown, Foo Fighters and Lil Wayne, might have started a good-natured dance-titan beef on the Grammys' red carpet.
It began when Deadmau5 arrived on the red carpet wearing (in addition to his trademark mouse helmet) a black T-shirt with a phone number and the phrase “U mad bro?,” a popular comeback in the darker corners of Internet prankster subculture.
The phone number, with a 626 area code, apparently belongs to his fellow Grammy-nominated dance artist Skrillex. Skrillex was a good sport about it — posing with Deadmau5 and applauding his gumption on Twitter.
Skrillex shouldn't feel too bad about the joke though — he won both major dance-music Grammys for his e.p. "Scary Monsters and Nice Sprites." That said, it's probably too late to call and congratulate him — the phone number’s mailbox is, naturally, over capacity now.
