Is this a joke?

I can't figure out if this is a joke or not!
The most disturbing thing is this little bit of information: "*Maximum weight capacity is 80 Kilos (approx.175 lbs.). Exceeding the recommended weight will void all warranties and may result in rupture of waste tank, possible bacterial contamination of briefcase contents, and massive stench."
Does that mean the person using the toilet can't exceed a body weight of 175 lbs or that the briefcase itself can hold only 175 lbs of waste? Either way...so disturbing.
