They'll probably have a name for the psychological reprecussions...like, maybe, tongue-splitting self esteem depreciation. What do you think?

(Tonguesplitese for "My degree is in business communication.")
My thought is that until the subject gets a handle on speaking with forked tongue, there'll be a lot of extra "trilling" due to the extra tip flapping around in his mouth, as well as lisping, extra hissing, and drooling through the split when he's trying to pronounce an "S".
On the other hand, who knows? Maybe yodeling will be easier for him, or them.
