I was sitting down at home minding my own business watching football (as you do) and the wife came in muttering about somthing or other (as she does) when I heared her say ..."and he wouldnt say boo to a goo"..

I turned down the TV and asked her to repeat what she had just said.
"Boo too a goo" she repeated..
Mystified !! Then my 17 yr old stepped in and told me that she meant
"Boo to a goose".
Ahhh!!!,
anyway I turned tv volume back up.
You get used to it after about 15 years.
