Boys are dumb

Tom buzzed his hair last night and he tells me today, "I never noticed it before but either my hands are really big or my head is small." Now, he has giant Shrek hands and I've told him that before (his pinky is the size of my thumb) but this time I just said "Your head's getting smaller. I didn't want to say anything but I've noticed." Now he's all paranoid that he's losing skull bone density or something. You'd think, since I didn't marry for looks, that he'd at least be smarter than this.
