So, as people will no doubt be aware after my recent postings on Facebook and in the Listening thread on here; my sister decided to abuse the privilege of being able to use my computer.

Now, the entertaining part is that whilst she has not left herself logged in her boyfriend of some years has done, and so a little revenge is called for. So the option of a status update on the boyfriend's page is definitely on the cards but it needs to be something to wind up my sister. My thoughts so far:

Post that my sister and boyfriend are now engaged.
Post that my sister is now pregnant.
Create a fake account of some sort of floozy and set her boyfriend to be married to the floozy.

Any other thoughts?

Engagement needs both people to confirm, so that won't work.

Pregnant? A good joke - may work.

Some kind of embarrassing disease?

I couldn't change their status to being engaged but I could still post an announcement.

I'm embarrassed to say that I actually thought you'd be listening to the Bieb. I almost looked up the album to see who produced it!

'He' should start slagging off her friends

Lots of thoughts..... None of which are in good taste.

Neither is suggesting that I might have been listening to Justin Bieber.

12 week scan photo has been uploaded.

Okay (I did warn you)...... You could intimate that she's allowed him to have anal sex with her..... Or that she's just just got a new piercing somewhere not generally on show..... Maybe mention of a third nipple......

(I'm assuming your sister is old enough for such jokes to be okay.)

Erm...

...unless the boyfriend was involved, it seems a little unfair to include him.

I like this. Combined with the pregnancy scans, it gives the option for some very heart-rending updates concerning his dilemma.

She should have a ridiculous name though, like Lady Penelope the Forth.

Generally, it should be ridiculous enough that to any sensible person it's obviously fake on a closer look. Your sister isn't a total retard is she?

does he have timeline? set his cover photo to gore/porn/furry/other silliness

change his gender, birthday, possibly name. i think you might need access to their email account to do this though, has he left that logged in too?

or alternatively put My Little Ponys everywhere. Pinkie Pie is my favourite and a good starting point.

I love Fluttershy. Are you a Bronie

The boyfriend was definitely involved. On both counts

as Big Mac would say, "eeeeyyup"

Pinkie was my absolute favourite in Season 1, but I think she got a little overused in Season 2. The others in the Mane 6 are pretty good, except for Rarity who is probably the least generous member of the cast despite having the Generosity element

Not having a facebook acount, I didn't know what Frape meant.

I actually thought you'd bought a new coffee machine, but couldn't spell Frappé.
