Pop quiz: What's better than watching One Direction perform "Live While We're Young"?
How about watching them sing it while engaging in a hilarious water fight!
The silliness happened on stage at the boys' recent concert in Paris.
Naughty Liam Payne started the trouble -- of course! -- attacking poor Harry Styles during his solo section in "What Makes You Beautiful."
Later in the show, he decided to splash some water on Zayn Malik and Louis Tomlinson during "Live While We're Young," which is captured in the clip above.
If you ask us, the best part of the video is the incredibly shocked look on Niall Horan's face. He knows by now that Liam is the prankster of the group. Maybe he's just afraid that he's next?!
We can't wait for the Take Me Home tour to hit the US this summer. Hopefully there will be plenty of crazy moments like this one!
