It's been a heartbreaking week for Bam Margera so far, and it isn't even Wednesday yet. Earlier this week Bam got what he described to MyFoxPhilly as 'the worst phone call of his life' when he got the news that his best friend and fellow Jackass star Ryan Dunn was killed in a tragic car accident. On top of dealing with the tragic news about his best friend, Bam has also made headlines for his reaction to insensitive tweets from Roger Ebert on Twitter. Bam visited to site of the crash today, and in his first interview since the accident he could barely put together a sentence. You can see the emotion in this video as tears stream down his face as he mourns the loss of his lifelong friend.
