We dont do duvets

Proof my husband has lost it!!!!!!!!! We were in bed last night and something got spilt on to the duvets and Ste shouts we don't do duvets!!!!!! to which i collapse in hysterics. for those of our age group who spent a lot of Saturday mornings in front of live and kicking they will remember Trevor and Simon and there laundry shop were the celebs always went to be told we don't do duvets. I have to say i didn't instantly remember where the saying came from but once i heard live and kicking i remembered.
