Must be fake. Why would he post that on youtube if it was real?
i agree they're fake...but why would you think the person in the vid is the one who posted it? if my friend shat his pants, and i had it on vid, it'd be me posting it to embarrass him, not himself posting it...
i hope the first one is fake, cuz if not that guy has serious health problems...the liquid starts off looking black then looks red on his hand...doesnt seem very healthy
