The other thing about the egg selling plot, in addition to the body-commodification theme, is that, as batyatoon put it when we were talking about this, it's like "you walk into a clinic to sell your eggs! And suddenly THREE HORRIBLE STRANGERS SHOW UP CALLING YOU 'MOM.'" I actually kind of love how much the movie, in its own lovable, bizarre, and deeply incoherent way, is centered on mothers and motherhood and all the complexities of that (as opposed to the usual DADDY ISSUES UP THE WAZOO.)
