In the beginning, things are already a little weird, the South African accent being just slightly off from what we know, and the guy seems a little aggro asking the nice lady about the gum: Like, what's his beef? But by the end you realize this is just his desperate attempt to find some answers to the purgatory he has inadvertently fallen into.
Of course, they want us to think their gum lasting long is a good thing, but it comes off as their gum will trap you in a place of abundant and delicious food where all you can do is walk around confused, chewing gum, forever. In other words, Stimorol gum, which already sounds like some medicine for a painful condition -- which you'd have to administer rectally -- will trap you in an eternal Sisyphean torment with no hope of escape. It's Infinity, try some.
