Apparently splitting the toungue will not give you any abilities you didnt already have. If you can roll your toungue, or better yet twist it (roll it over), then that shows some extra control of those muscles which can be interesting to play with once its split. But if all you can do is stick it out then thats going to be about it. The one that most people DO have is flatten-it, point-it, flatten-it, point-it. If you practice that with a split toungue you get neat effect. Whats real fun is that if you stick it out "pointed" then its easy to overlook that its not a normal toungue, then spread the forks (flatten it) for the look on their faces.
(no, I dont have one. Ive never needed artificial means to fit in just fine with the strange crowd)
