Ever see an episode of Family Guy that kinda corresponds to what you just said?
Ok, Peter has to go to this retreat with women to become more sensitive towards women, and a lady tells him that giving birth is similar to pulling your lower lip over your head.
Well, ironically Peter falls out of a tree and snags his lip on a branch, which pulls it over his face. I was laughing so hard, I sneezed and snot ran down my chin.
*pardon the gross snot part*
