I noticed the other day when Alison and Kate were lting in bed (oo err) and chatting that the E4 coverage kept cutting out. When it was shown on C4 the next day, it was revealed and there were no rude words or defamatory remarks. advertising etc
Here is my theory. E4 are just p*****g about, dipping the sound (and substituting with farmyard noises) to intrigue everyone.
Example Jade: "Did you hear what Alex said to me, he said... *twitt twoo twitt twoo squawk squawk baaaaaaa baaaaaa* and then I said to him *boc boc boc boc twitt twooo*
