Just cuss like a trooper on Twitter, add #fuckfamine and those darn clever folk over at SwearJar (brought to you by the 50/50 Good Project) will track you over a week, charging a mere £1 per swear.

And I like the fact that if anyone retweets they get charged. Effing brilliant and all for an effing good cause.
