I was driving with my 6year old grandson and beeped the horn by mistake.
He turned and looked at me.
"I did that by accident." I said
"I know, Popa."
I said, "How did you know that?"
"Because you didn't yell '*******' afterwards".

My dad was visiting my sister and they were driving with my 4 year old nephew. He said plain as day and oblivious to all "Hey Mom tickle my nuts!" My sister said with a grin That was not appropriate. They then pulled over and my dad and sister got out of car to laugh.

to both above

the one about the horn - I will have to tell my dad that he will like it..

My daughter was always little (til she hit her teen years anyway) so she got called "Dinky Little Girl", which got shortened to "The Dink" or just Dink. One Xmas, my ex, the kids, and I were headed to the WalMart. At the entrance, there'* a double left turn lane. We were on the inside lane. The moron in the outside lane decided he needed to be in our lane as we were all turning. The Ex screamed at him "You #*^%ing Dink!!" A little voice from the back seat whispered "What, mommy??"
