I just heard dating advice from the open door from a substitute

"Never buy popcorn at the movies!"
"Never buy ribs on a date!"
"Men, never date a girl who has a tattoo of a dagger on her body!"
"Girls, never date a guy who has lipstick stain on his body!"
"Never date a person who has an ex's name tattooed on their body!"
"Never date a person who's name is also the name of a city!"
