That's when you tell grandma, " thanks we ll celebrate her pregnancy and the succes of your surgery together. We just found that you need one"

Just sit her down and tell her the truth.... PSYCHE! we all know that never works on women.

FFS. We need that damn old people category FML. MAKE ONE PLEASEEEEEE

So disturbing.

And what precisely is "so disturbing", 39?

I completely agree! It would be a hit, old people say the darndest things. :)

Damn, replied to the wrong comment. So sorry #1 :)

I forgive you. That's the first time I've been called number 1 since smitty werbenjagermanjensen stole my hat

That was all-around stupid.

That would probably just hurt both relationships even more.... Actually, your grandmother might just go with it and anger your girlfriend even more.

Why does this idea even have any thumbs up?

Explain to you are girlfriend?

So, shouldn't she realize that if you were in fact married, and she's the other woman, that you wouldn't be bringing her to a FAMILY dinner? I'm sure if you talk to her she'll be fine.

No, the whole family's in on it, they support him leading two lives because they want a bigger family. Dinner with the wife is Monday, Wednesday, and all weekend. The girlfriend get Tuesday, Thursday, and Friday.

How do you know she's not? Maybe both of you just never thought of it. I know it never occurred to me to have a prank war with my grandmother. She is cool enough to have pierced her belly button for her 60th birthday though, maybe she'd be up for it :P

Old people need to have fun too! I'd imagine sitting in a recliner watching Matlock and eating soft foods all day gets pretty boring after a while.

I blame Betty White and "Off Their Rockers" for all these grandparent related fmls.

Troll Grandma: +2, Girlfriend that's in on the prank: +1

Oh so your grandma makes a joke and you threaten to kick her out? I just hope this mentality doesn't hit you back as karma. Yes OP should talk to the grandma about not making such jokes but drive her to the nursing home?

That will only work if Norm MacDonald is the Grim Reaper. Either way, keep an AICD handy. You may need it.

"Don't get mad, get even." I like it!

Coffins are too damn expensive. Although I suppose he could get her measurements and be prepared for that unfortunate day when epic gran is lost to us.
