Unless I miss my guess, Monkey's true identity is an anagram of 'A Gassy Ape', plus a whole bunch of other letters left over which I can't make anything interesting out of (well, actually I can, but I don't want to fill in any of the remaining blanks). I'm not gonna name names though, just in case he goes De Niro-in-Untouchables on me with that little baseball bat of his...
