The viral 10-year-challenge, in which people share side by side photos taken at least 10 years apart, is all the rage on social media this week. 

Arabs naturally joined in on the "then and now" trend ... and some of them are adding their own humorous touch to it.

Their twist on the challenge will definitely make you LOL: 

1. Arab humor for the win!

"Subhanallah, I haven't changed."

2. Going downhill is an understatement for some

3. Like way downhill

4. On constants

5. For others, change is the only constant

6. Lebanon's Nabih Berri never seems to age

7. Arab wallets be like

8. New activities have definitely made their way

9. The development of "Arab health" trend

10. Some people travel back in time

11. Henedy won this challenge

12. Shima Saif hilariously roasted it

13. Some Lebanese problems never change

14. "After seeing a 10-year-old photo"
