I know there are videos of one directions funniest moments on fanpop but some people pefer to read so this is for people who like to read.
During a behind the scenes video one direction were sitting back on deck chairs out the back near the pool and what makes you beautiful was in the background and when it got to the chorus in their clothes they jumped in the pool and started swimming around and having fun and at the end Harry swam up to the edge and said "if you wanna see more behind the scenes stuff like this subscibe to heatworld on youtube" and the funniest thing was he couldn't see because his hair was in his eyes
