#2935: Ocean Loop

XKCD comic, described below.
Transcript

[A cruise ship approaches an enormous loop-de-loop flume from the left. A large jet of water is being propelled into the loop-de-loop by an enormous submerged hot tub style jet. The loop-de-loop, that looks like a waterslide, and the structure housing the jet are connected to a slightly inclined seabed, higher on the right.]

[Caption below the panel:]

I don't know why the cruise line fired me.

I can't believe they wouldn't even let me hold a vote among the passengers about whether to try the loop.
