In many situations in the old The Simpsons episodes, Bart inexplicably speaks a sentence in British, out of the blue. For example:
You mean it ain't me noggin', it's me peepers?
(After his American teacher states that she suspects that Bart's apparent slow-wittedness may have been the result of a simple eyesight problem.)
Nothing about the context seems to warrant him speaking in a very British manner, and he only ever does it for a "line" or two.
Obviously, it "sounds funny", but is there some deeper meaning behind this which I'm missing? Bart, the character, simply thinks it's funny to speak like a British person sometimes? Is it meant to symbolize something?
