Me and one of my flatmates at Uni had a few months of competetively trying to gross each other out by drawing detailed incestuous drawings of Bart and Lisa Simpson on each other's Bebo walls (if no one remembers Bebo, it was like a sh*t version of Facebook, and you could draw MSPaint-style pictures).

Then Bebo shut down, so you couldn't log in to delete anything but the pages were still up, and I worried for a while that one day I'd go for a job interview and they'd be like "Please leave the building immediately sir, we googled your name and found FILTH!!"

Thankfully... Bebo doesn't exist at all any more. Whew!
