How I Met Your Mother : How Do You Keep A Girl From Becoming Your Girlfriend?
Barney: How do you keep a girl from becoming your girlfriend? Simple: The rules for girls are the same as Gremlins. Rule number one: Never get them wet. In other words, don’t let her take a shower in your place. Rule number two: Keep them away from sunlight—i.e., don’t ever see them during the day. And rule number three: Never feed them after midnight. Meaning she doesn’t sleep over, and you don’t have breakfast with her, ever.
Ted: What about brunch? Is brunch cool?
Barney: No, Ted, brunch is not cool.
