Soap fans don't miss a trick, do they?
You can't sneak any mistake past eagle-eyed viewers at home, no matter how small or insignificant an error it is.
Eastenders fans were quick to spot a
cock up on Albert Square as Sharon was making in the run up to Grant Mitchell's return.
They noticed she was actually calling off her phone's notebook function, which is a bit daft if you've ever tried it.

Emmerdale fans pointed out the fake rain at James's funeral last week as brilliant blue and cloudless sky shone out in the background.

But this week it was those ever-observant Coronation Street who noticed a mistake in the ITV show the other night.
We're not going to give the game away just yet, but see if you can spot what's wrong in this clip posted by OK Magazine.
We would never have spotted it to be fair, but hardcore Corrie fans watching the scene where character Anna Windass returned home from hospital spotted it straight away.
Anna, who suffered terrible burns to her legs in a shocking accident, was trying to get up to get some water and was struggling a bit.
Corrie fans wondered if it was down to the fact that she was using her crutches backwards.
