Kanye West tweets angrily at Jimmy Kimmel

Kanye West launched a Twitter tirade against Jimmy Kimmel on Thursday after the late-night funnyman spoofed West in a video segment on Tuesday's Jimmy Kimmel Live.

Unless it's all an elaborate prank, West was apparently angered by this video, which makes fun of the rapper's recent interview with BBC Radio 1's Zane Lowe in which West describes himself as the "biggest" rock star ever.
