Quote from Jerry in The Smelly Car
[stand-up:] Jerry: Whenever you ask for a doggy bag in a restaurant, there's a certain sense of failure there, isn't there? People always whisper it to the waiter, don't they? [quietly] "Uh, excuse me. I'm sorry, you're gonna have to give me the doggy bag. I couldn't make it." And it is embarrassing, because a doggie bag means either you are out at a restaurant when you aren't hungry, or you've chosen the stupidest possible way to get dog food that there is. How about the doggie bag on a date? That's a good move for a guy, huh? Let me tell you something: if you're a guy and you ask for the doggie bag on a date, you might as well have them just wrap up your genitals too. You're not going to be needing those for awhile, either.
