Cxanadu can inflate himself to a shocking size even among stuffer boys. You can always tell it's him by the way he has to lean way back to compensate for all the weight in front.
The comments for this particular video are rather funny in that no one can figure out whether this is actually something someone can do:
berit542: guys its a different guy
cman18000: it's two different people, watch carefully at 0:17, the skin color changes
What do you think, all you stuffies, gainers, and drooling FAs? Shouldn't something that stretches the human body this much out of shape be fictional?
