Irish is a really fun language to learn. Starting Irish will be very tough. However it gets a lot easier. You can even listen to pronunciation on RTE's internet radio.
LostYourName, you have to be one of the only other people I know who learned Cherokee. As a child I grew up around Tahlequah OK so my school was about 80% Cherokee. I had Cherokee lessons from 3rd grade until Jr. High. I personally did not like the language. I was really young so any second language probably seemed pointless to me. I can't say I suggest Cherokee though.
Irish would be the easiest language to learn, with correct pronunciation, for bragging rights. However it is not too dead. On the islands just off of western Ireland the traffic signs are pure Irish. However it is dead enough to rock. And in my opinion the coolest sounding language.
