Does exactly what it says on the tin

You may have seen the recent television advert with Vinnie Jones for the British Heart Foundation. Doing chest compressions to the tune of Staying Alive. Well the BHF are selling these t-shirts which are utterly fab in my opinion... I also got a mans version which caused huge laughter at work as it has hard & fast printed on fists which sit across... Well you can imagine where that might appear on a girl.
