Yeah I have to agree it maybe funny but I think the reason that someone would let someone else do that to them is because they don't have very good self esteem and so in return they don't care about their own body. You should try encouraging him to workout with you sometime and try to get in shape I think that will benefit his quality of life more than getting over 4,000 views on a video of him with the caption "Fat kid lets free-runner wallflip on his nuts!!!". IDK that's just my two cents,

stuff like this makes parkour and free running look like viva la bam crap.
