1. Masturbating, I was wondering why the building suddenly started shaking... 2. My most classic moment: I was taking a shit, just halfway through... 3. Surfing the internet 4. Listening to DJ music, and I was headbanging but then felt like I didn't need drugs anymore... Only later did I realize it was an earthquake... 5. Masturbating, right at the peak of pleasure when the shaking started, and then I cummed...
