Please give me some good arguments--pithy and humorous, especially--about why the wheel should be (Edit)reinvented.

I am so sick and tired of hearing people argue against change because "We don't need to reinvent the wheel."

I'm also sick and tired of hearing people argue that 'you don't have to be a rocket scientist to understand so and so'--but that's another matter.

I'd just like a good zinger to throw back at people who regularly say we don't need to reinvent the wheel, especially if I see problems with the wheel in question.

Thanks for coming up with a zinger if you can.
