This week's cap comp features Australian swimming star Ian Thorpe as he sits pool-side with a furry friend.
The 'Thorpedo', who bagged five medals at the Sydney Olympics in 2000, will be hoping to go one better in Athens.
But the 21-year-old will face stern competition from America's Michael Phelps, who recently took over Thorpe's mantle as world number one.
Here we see Thorpe relaxing with friends at the Olympic team trials earlier in the year in Sydney - and we want you to tell us what's going on as he is joined by friendly koala bear.
This week's winner is Nicola Chisholm from the UK who quipped:
Thorpe enjoys some koala-ty time with friends
Congratulations Nicola, the BBC goody bag's on its way to you!
A new cap comp will be published on Tuesday.
