I'm going to take a guess at:

"....
Clowns to the left of me,
Jokers to the right,

Stuck in the Middle with you....."

A caution regarding the disassembly video linked to in my previous post and the use of acetone.  The video stated the acetone ruined the finish on the exterior but they used acetone to help remove the rear section of the front lens assembly.  However if the interior parts are also of the same type of plastic, acetone could weld the threads together rather than loosening them.  Since I have not opened up the lens, I cannot comment further, but this is just a caution.
