Seismology and Valentine's Day

Here are some questions for all the geologists out there:

1) Can the symphony of love-making that occurs worldwide on Valentine's Day be detected using seismographs?
2) Have geologists ever confused such a phenomenon with an earthquake?
3) Does the phrase "If the room is rockin', don't come a-knockin'" have special significance to geologists?

Thanks to the scientific community in advance...
