"Timothy Tester" was a strip that ran in Whizzer and Chips. An entry in the ever-popular "kid with weird hobby" genre, the strip starred a boy who was intent on performing tests involving various objects (for example, seeing what happens when you put spaghetti through a knitting machine). It was drawn by Cliff Brown.
The premise was maybe a little too thin to catch on: Bustercomic.co.uk named "Timothy Tester" as runner-up for Most Disappointing Strip in Whizzer and Chips. Oh well.
