Not-so-Great Pretenders

No, I can't believe your success either

Could you tell me what there is to like about impressionists? No, not the French painting variety, for Christ's sake, I mean the people who put on the voices and twitches of slebs. No really, could you tell me what there is to like? Because I am at a complete and utter bloody loss about why they enjoy national popularity.
I'd rather watch my ovaries being removed via my nostrils than be exposed to un-funny men like John Culshaw and Alistair McGowan. Problem is that their impersonations are nothing less than shite. 
Their voices and actions leave me either bewildered or cold and, worse, they try to make up for it by injecting dull yet explanatory jokes into their acts. You know the sort of thing. The obligatory Bruce Forsythe turn will include references to Strictly Come Dancing and "NIce to see you!" catchphrases because the impression itself is so fucking poor that you'd otherwise have no clue about who it's supposed to be. They'd be better off broadcasting a blank screen and letting viewers use their fevered imaginations. 
In one alleged comedy show - Punt and Dennis, I recall through my frustrated tears - the few attempted impressions were so horrifyingly inaccurate that they actually introduced each sketch with screen captions. What in the fuck were they thinking? Didn't it cross their fame-hungry minds that if their offerings were that poor they should be scrapped? 
This goes for every impressionist, though, doesn't it? They're all laughably bad yet someone, somewhere keeps commissioning the bastards. I suspect that in the land of the blind the one-eyed man is king. There's such a dearth of decent impressionists that any old twat with a passing resemblance to Anne Robinson gets a gig.
Tell you what these guys should do and that's do an impression of being good at something. I dunno, emptying bins or architecture will do. Anything except assaulting the nation with their deluded witterings. Or they could try the French painting. As long as they piss off to France, that is.
