Question: How many copies of a Darin song did the first Swedish citizen in space take with him?
Context: The cosmological interpretation of quantum mechanics, proposed by Anthony Aguirre and Max Tegmark, is an interpretation of quantum mechanics that applies in the context of eternal cosmological inflation, which arguably predicts an infinite three-dimensional space with infinitely many planets and infinitely many copies of any quantum system.  According to this interpretation, the wavefunction for a quantum system describes not some imaginary ensemble of possibilities for what the system might be doing, but rather the actual spatial collection of identical copies of the system that exist in our infinite space.  Its collapse can be avoided.  Moreover, the quantum uncertainty that you experience simply reflects your inability to self-locate in space, i.e., to know which of your infinitely many copies throughout space is the one having your subjective perceptions.

It was written with DJ Murray the K (Murray Kaufman), who bet that Darin could not write a song that began with the words, "Splish Splash, I was takin' a bath", as suggested by Murray's mother, Jean Kaufman.  The song was credited to Darin and "Jean Murray" (a combination of their names) to avoid any hint of payola.  It was Darin's first hit and the song helped to give him a major boost in his career, reaching No. 3 on the U.S. pop singles chart and No. 2 on the R&B Best Sellers chart.  "Splish Splash" was Darin's only entry on the C&W Best Sellers in Stores chart, where it peaked at No. 14.  In a 1967 interview, Darin claimed that he was so happy about having his first hit that his skin condition cleared up.
