Brandon Cole "Bam" Margera[2] (/mɑːrˈdʒɛərə/ mar-JAIR-ə; born September 28, 1979),

is an American skateboarder, stunt performer, television personality, and filmmaker.

 He came to prominence in the early 2000s as one of the stars of the MTV reality stunt show Jackass and,

subsequent sequels. He also created the Jackass spin-off shows Viva La Bam,

Bam's Unholy Union, Bam's World Domination, and Bam's Bad Ass

Margera was born on September 28, 1979[3] in West Chester, Pennsylvania,[citation needed,

 the son of April (née Cole) and Phil Margera. He is the younger brother of Jess Margera and nephew,

Vincent "Don Vito" Margera. His grandfather nicknamed him "Bam Bam" at

the age of three after noticing his habit of purposely running into walls; over time,

that nickname was shortened to "Bam" by his schoolmates.

Margera dropped out of high school after his junior year, but was homeschooled by his mother and received his GED,

Margera began shooting videos of himself and his friends skateboarding and doing stunts,

which eventually turned into the CKY video series. He independently released CKY.

CKY2K, CKY3 and CKY4 have also been released. CKY stands for "Camp Kill Yourself",

name shared with his brother Jess Margera's band, CKY, which was named as a tribute to,

the film Sleepaway Camp. These early videos feature many of Margera's friends,

 including Ryan Dunn, Brandon DiCamillo, Rake Yohn, Chris Raab, and Brandon Novak,

who form a loose collective known as the CKY crew. The video and band projects are heavily interlinked.

Following CKY's success, former Big Brother editor Jeff Tremaine noticed Margera's videos and drafted him into,

 the team that would eventually become MTV's Jackass. Margera and Ryan Dunn became mainstays of,

the cast while other CKY crew members played supporting roles to various degrees.
