Panel 1: We find ourselves at a farmer's market today as Lizzie tells Mike to lookit at the pun'kins 'cause Daddy said they can get one each this year again.
Panel 2: Mike says that he's tryin'to find one with the right personality.
Panel 3: The problem is that it's like trying to imagine someone's face from the back of their head.
Summary: What he probably means is that he won't know what it'll look like until it's carved and thus worries about the thing being a disappointment.
