IE and firefox are just like these ripoffs:
Ford - Mercury (copies EVERY vehicle)
Chevy - GM
Chrysler - Dodge (sort of)
Facebook - myspace (fb came up with the new stuff [quizzes, bumper stickers, etc], myspace is dead, so they're trying to copy fb to get it busy again)
Netflix - Blockbuster thing like netflix
I could name a million other things but my brain isn't thinking now.
