Hi Vianne, 'Kind words butter no parsnips' means when you are trying to win round someone with flattery. A lovely saying that I learnt from my sister.
Hi Dyan, 'Don't look at me with that tone of voice' can be continued with
'It smells a funny colour'!!!! 
Thanks, marras, i've wondered about that one for years!!

Another one i like is, "well, i'll go to the foot of our stairs!"
