It all started when Patrick Carney (the drummer for The Black Keys) said that he didn't think Justin Bieber deserved a Grammy. Then, JB tweeted that he thought Carney needed to be slapped.

Now, all hell has broken loose on twitter.

Patrick Carney... has become... Justin Bieber... on twttiter. 

According to TMZ:

Carney's handiwork has annoyed both his fans and Bieber's, prompting tweets like:

-- "I used to like you, but why are you being such a d**k?"
-- "do you even know how stupid and immature u look doing this. arent u like fifty?"
-- "do you know how f**king dumb your acting and how stupid you look lmao"
-- "Can we please have Patrick back?"

Gotta ask... funny? disrespectful or both?
