Bam Margera -- Privates Screening of 'Jackass 3D'

Bam Margera's nearest and dearest just got their first whiff of the latest bone-crushing "Jackass" installment ... thanks to an invite-only screening set up by Bam himself.

Bam held the private screening of "Jackass 3D" on Tuesday night in his hometown of West Chester, PA -- where a theater full of people ... including his mother/co-star April ... showed up to check it out.

Hopefully, someone gave Bam a giant high five for setting it up.
