I'm not talking about farting here. What is the weirdest sound that's ever organically come from your body - did you ever hear a bone break or hear something collapse or pop? Let's try and keep it PG, as I realize this could go to a bad place. I ask because my cartilage pops in my ribs right now when our baby moves a lot. It sounds like a knee popping or someone clipping their fingernails. It's bizarre.
