But having been challenged to join in the mischief created in a Twitter thread by @2hrTV following a plea from @The_Cybermatt to Terrance Dicks to stop using the word Melkur in his chapter titles for the novelisation of Doctor Who and the Keeper of Traken (!), I couldn't resist knocking up some visuals for Melkur ITV sitcoms... as you do.
They're all based on Network DVD covers... and I've included a Frankie Howerd one at @2hrTV's request...

You can understand how even the funniest joke can wear very thin after a short period of time.
But then again, that's Twitter humour for you...
