i know your mother
something old farts yell when they see you get wrecked or crash their rusty hunk of junk
My uncle screamed 'I know your mother' when I totaled his car into a mailbox.
At the park, the old man yelled 'I know your mother' after I kicked his leg out from under him.
My grandma said 'I know your mother' when I spilled soup on her favorite sweater.
