For people out of the know: the poop was because a person asked for help how not to poop for 3 days because he had no access or didn't want to during a hike.
The Titan submarine because their visit to the Titanic was prolonged indefinitely/they wanted to meet the victims in person.
The beans I'm curious for, so if anybody knows...
My guess is that r/beansinthings migrated as a group and started shitposting. It's funny at first, but quickly becomes either a sad waste of beans or unpleasantly disgusting. If I'm being honest it' usually a combination of the two.
