I think it's funny that probably 99% of these I have heard.
My Grandfather used to like to say something would "Gag a maggot" meaning it was really bad.
My great-grandfather used to say "You lika lice?" when talking about rice. (My grandmother never could eat rice after that!)
My grandmother used to threaten us kids with "Keep it up & I'll break your arm in 3 places" meaning we were one step shy of her using our middle names! (Then we REALLY knew we were in trouble!)
My grandfather was from the southern US. and used to say he was 21 years old before he learned that Damn Yankee was 2 words!
Looks like my grandfather was not PC & my grandmother would probably get arrested for child abuse! How things have changed!
