Jackass star Bam Margera gave his very inebriated "best friend" a flying kick after socking him in each eye and pants-ing him on the street in front of Teddy's last night.

Course, this was all in good fun -- and all in a day's work -- for the Jackasses who are currently shooting Jackass 3-D. You HAVE to watch the NSFW vid above (if you dare).
