HI Guys
,
I saw the click to donate a mammogram thread so I decided to show you guys this.
www.freerice.com 
It's a website where for every question you get right, 10 grains of rice gets donated to try and stop World Hunger in places like Africa and Syria, etc.
I think we should all have a go at it, It's pretty fun too.
Proof that it isn't a hoax:

Also, Please disable adblock on that website as the advertiser funds the rice.
