Can you come up with a caption for this week's competition?
This week's picture shows Bolivian black-capped squirrel monkeys playing with an England-themed football at London Zoo.
What do you think the monkeys are thinking as they push the ball around?
Let us know now!
Last week's winning entries
Last week's picture showed a Chinese girl dressed up as one of the Beijing 2008 Olympic Games mascots during Children's Day celebrations which are held in China on 1 June.
There were loads of really great captions but we had to make a choice - and here are your best captions:
Now that's what you call a support England outfit!
Pipa, 15, Cornwall
I'm a little teapot, short and stout!
Chloe, 10, Ludlow
When they said do I want to be in the Olympics I thought they meant I would compete not dress up as a red pepper!
George, 14, Windsor
