On the episode that talks about when Homer was in the Bee Sharps, I could have sworn that he said to Bart, “What did I say about swearing like a 19th century shoe black?” or something along those lines. But when I saw it just now, he said “What did I say about swearing like a grizzled 1890′s prospector?” and it even looked like the part didn’t lip sync correctly (though in those earlier episodes, the lip syncing wasn’t exactly perfect). Am I witnessing an easter egg?

Hmm…
