"Jabberwocky" at 2 1/2

I don't often talk a lot about my son online--it would be far too easy to bore people with all the things I find funny or cute or whatever. But I do have to mention that at supper today he said out of the blue, "'Twas brillig." (We have a picture book version of Jabberwocky from the library that I picked out last time we were there.) By the end of the meal he was saying, "'Twas brillig and the slithy toves did gyre and gimble." But when I tried to continue on from there he told me, "No, that's not right." So far trying to call him my beamish boy hasn't caught on. Now I think of it, though, he was having fun with frabjous, callooh and callay the other day.
