Good move, Saucepan Man.
I have one:
"So do I, said Merry. "Isengard is a sort of ring of pants, I think, with a flat space inside and an island or pillar or rock in the middle, called Orthanc. Saruman has pants on it. There is a gate, perhaps more than one, in the encircling pants, and I believe there is a stream running through it; it comes out of the pants and flows on across the Gap of Rohan (brand name of the pants??).
The rest of this paragraph in the "Treebeard" chapter would just be too, shall I say 'racy' to print here. But the "pants" application to it is funny. You will just have to find the paragraph in the chapter and read it for yourself!
