Ian Dempsey has revealed his dare for Today FM's Dare to care campaign.

He's prepared to get a tattoo after being dared by thousands of listeners! But only if he raises €25,000 for the Irish cancer society.

He's set up a fundraising page justgiving.com/dare to care.

So it's official - @IanDempsey is to get his FIRST TATTOO for #DareToCare

But only if we raise 25k - let's do this! pic.twitter.com/s6mawgZtZY

But what are the other presenters doing?

Kim Buckley had a chat with them:

This September, Today FM will Dare to Care and we want you to do the same.

We’ll push ourselves outside of our comfort zones, dare ourselves and be dared. And we'll do it to support cancer patients and their families across Ireland through the work of the Irish Cancer Society.
