I'd like to think that people know that this stuff is (most likely) not real, but some people can chime in and provide interesting information anyway. The top comment (about being trained in working in confined spaces and asphyxiation hazards) is new information to me, for example.

In my opinion, this kind of entertainment is in the same class as morning talk show sketches like "Second Date Update." It's obviously fake (who would agree to talk about a date on the radio from a random caller?), but it's hilarious and, for some, an interesting thing to talk about with friends who might even have similarly crazy stories that are actually real.
