I sometimes say "muscles" so that the 'c' has a 'k' sound (the same way the cartoon character Popeye says it), computor instead of "computer" (after Ned Beatty's exaggerated pronunciation of "Mr Luthor" in the Superman movies), and I occasionally say benimber instead of "remember" because it was something my cousin Paul said more than 20 years ago.
Don't miss the excellent comments tail. This is something I do all the time. Far too many examples to list. A product, perhaps, of speaking and hearing foreign languages all day every day. Though kottke has so many people who do it too. It must just be something peeps do.
