Behind the scenes
Dez Skinn wears platform slippers (comically labelled as such, as though this needed pointing out) as he goes to bed in the comic story The Origin of Doctor Who Magazine, printed in DWM 544 to celebrate the 40th anniversary of Doctor Who Magazine. However, due to its parodical nature, this story is not currently considered a valid source for in-universe articles by our Wiki.
