The doom and gloom brigade:
Me:
Them: IT'S ONLY GOING TO GET WORSE.
FIL when finding out we were having a girl: Oh that's such a shame for [DH].
Me:
and why is that?
FIL: Oh well he won't be able to do anything with a girl, they don't play.
Me:

FIL, when I had the audacity to have a chippy tea in the early months: You'll need to watch your figure, you don't want to disappoint your husband by becoming fat.
Me: grrrrrrrr
My DM: You'll have to have an epidural, they let you have your husband in the delivery suite if you have an epidural you see.
Said in a way that seemed to imply the epidural was a way of making a labouring woman behave herself in an appropriate manner so that her husband would not be appalled by her behaviour. 
My DM, ever since I got past 12 weeks, said with enthusiasm and glee: You could deliver at any time!
At 25 weeks plus: Oh I'm so excited, you could give birth any day now!
Me, mentally, over and over, and then very loud ranting once she'd gone: WHY do you want me to have such a premature baby that she would have to be hooked up to all kinds of wires, tubes and monitors just to SURVIVE let alone thrive????
Not sure I'll ever forgive her for that. I'm 38 weeks now. Apparently I'll give birth on Sunday according to her, think as long as I give birth before my due date, she'll be able to smugly say she predicted an early birth for the rest of time. On Sunday I am sitting down and concentrating on keeping my cervix and general fanjo area well and truly shut, aside from wee breaks...
Sorry for the major ranting but ohhhhhhh that feels better!
