'Mishmash' = Paula Poundstone?

Every time I watch Brave Little Toaster, I see the "Mishmash" character ("I'm a can-opener, lamp, and shaver!") and hear what sounds like an imitation of Paula Poundstone. I know Mishmash is played by a voice actor, but since we have characters spoofing Peter Lorrie and Jack Nicholson, I wonder if it was intentional. This was about the time period where Poundstone was famous.
