Sadly, can't open the link without a password.
But, if I had a guess, I would say it's the standard "Funny Complaints by cruise passengers" list that's been around for years (many of which the cruise director repeats at some point in the cruise):
What would happen if I flushed a ship toilet while still sitting on it?
Does the crew sleep on board?
Why is the microwave in my room not working? (That's the safe)
Why did I pay so much to have such an awful view of the parking lot?
have an ‘Outside Cabin.’ Will I get wet if it rains?
What do you do with the ice carvings after they melt?
How do I know which are mine? (Regarding the photos on display in the photo gallery)
Do these stairs go up?
I booked an oceanview room and all I can see is the dock.
(and so on)
