Personally, as long as people are polite and a little romantic when needed, why not just have a little fun. Then again, I have actually had the following rules read out to me before by the father of a certain girl.
If you want to date my daughter, be aware of the following rules:
1. If you pull into my driveway and honk, you better be delivering a package, because you aren't picking anything up.
2. You do not touch my daughter in front of me. You may glance at her, as long as you keep it above the neck. If you can't keep your hands to yourself, I will remove them.
3. While it is fashionable for young men to wear their pants low, if I see this I will think of your dignity and use a nail gun to ensure your pants don't fall off accidently during your date with my daughter.
4. I'm sure you've been told that in today's world safe without a "barrier method" can kill you. Let me elaborate. When it comes to sex, I am the barrier and I will kill you.
5. It is expected we should talk about sport, politics and other trivial issues to get to know each other. Please don't do this. The only information I require is when you will have my daughter safe at home. You need only respond with the word "early".
6. I'm sure you have many opportunities to date other girls. But once you have dated my daughter, you will continue to date her until she is done with you. If you make her cry, I will make you cry.
7. As you stand in the hallway waiting for my daughter to get ready, do not sigh. If you wanted to be in time for the movie, you should not be dating. She is putting on her makeup, which can longer than painting the Sydney Harbour Bridge. Why don't you do something useful, like change the oil in my car?
8. You are not to take my daughter on any date where the surface you may sit on is softer than a wooden stool. You may not go anywhere where there are no parents or nuns. Romantic movies are a no-go, but violent ones are ok. Old folks homes are better.
9. Do not lie to me about anything that concerns the welfare of my daughter. I may be a balding old man, but I have a shotgun, a shovel and 10 acres of land out back.
10. Be afraid. Be very afraid.
He was kidding... I hope.
