How do you 'change' your facebook profile picture the same picture it was already?

[Allie]

Sometimes on my newsfeed, it says '___ updated their profile picture' but they updated it to the picture they originally had (as in there was no change), but they do it so that they show up on their newsfeed to get more likes etc.
How do you do this without deleting your comments and likes

its easy. please follow the instruction
1. login in facbook
2. go to your facebook profile
3. put the mouse pointer on your facebook profile picture without any click.
