I remember being in labor with my first, lying in a semi-dark room with strict orders to stay on my left side. I was in a lot of pain, obviously, and panting and moaning through each contraction. My H was holding my hand, and after one particularly bad contraction, while I was catching my breath, he sort of laughed and said, "Boy, I guess after this, you won't be having any more babies, will ya??" Butt head.
Kind of the same thing with Baby #4, when I was having my first birth center birth. Different H this time, but when things started really kicking into transition, and I was in the tub with the jets on, he leaned over and said, "Betcha wish you'd done that hospital thing with the epidural now, don't ya?" He's quite lucky I didn't grab the back of his head and drown him in the birth tub right then.
