That's 67 celsius, perfectly normal. If it goes above 85 celsius (185 F) you should start to worry.
 
Mine usually stays somewhere around 118F when the only applications open are Safari iTunes and iChat. When I have other programs or a video chat open the temp jumps up to 130F. The highest I have ever seen mine go is 138F. I keep it elevated all the time and use SMC fan control to keep the fans at a 3000 rpm minimum.
