Speaking of ending sentences with prepositions, you may have heard the one about the southern lady having a conversation with an aristocratic Northern blueblood.
"Where are y'all from?" she asks.
The Northern lady sticks her nose in the air and replies, "I am from a place where we do not end our sentences in prepositions."
To which the Southern lady replies, "Oh, pardon me! Where y'all from ... bitch!"
That’s a good one. :D
