First off, yes this kid sucks and its damn disgraceful but don't you EVER talk about weight or call someone chubby. I've had a weight problem all my life, the Sh*t i've been through because of it is insane... I will not let someone make fun of someone who has the same issues I do and must fight the same battles...
As far as Mercury goes.
I just personally worked out my own handling of this yesterday and really don't think that its that bad of an effect. The big mistake made here was admitted, he got the dvd and waited until his "hands were big enough" and then filmed a video... all of the problems lay right there.
