If you fancy feeling old, then let me be the one to tell you that Erik Per Sullivan - better known as Dewey from Malcolm in the Middle - is 30.

Which, I think, means I should be drawing my pension next week.

Baby-faced Erik hit our screens in the early 2000s, playing the youngest brother in the dysfunctional Wilkerson family alongside older brothers Francis (played by Christopher Kennedy Masterson), Reece (Justin Berfield) and Malcolm (played by Frankie Muniz).
