No, really, there is a Doctor Who Mr Potato Head. I can't make this stuff up!

If you cut him into fries, does he regenerate back into a whole potato?

If he does, he'll get cut up into fries again!

What about Potatoheaded-Bobby Brown?

BTW - I remember when the Mr Potato Head kit was comprised of stickpin parts and you had to supply your own vegetable!

i'm waiting for the ninth Doctor potato head or the Zappa potatohead (which will never happen, sadly)
