I found this on the ever-truthful intarwebs. Keep in mind it's a really crappy translation from German (really it's just English from a German who isn't fluent in English):
28 WAYS TO MAKE A GIRL SMILE.
 tell her she is BEAUTIFUL. not hott or fine.
 hold her hand at ANY moment even if it is just for a second.
 KISS her on the forehead
 leave her voice messages to wake up to.
 ALWAYS tell her you love her at any & and all times.
 when she is upset, hold her tight & tell her how much she means to u
 recognize the small thingsz ..they usually mean the most.
 call her BABE.
 SING to her no matter how horrible your voice is
 pick her over all the OTHER girls you hang out with
 write her NOTES. (she loves them)
 introduce her to family & friends as your girlfriend
 play with her hair.
 pick her up, tickle her, & PLAY WRESTLE with her.
 sit in the park & just TALK to her.
 tell her funny jokes, tell her stupid jokes, just tell her JOKES
 throw pebbles at her window in the middle of the night just because u missed her.
 let her fall asleep in your arms
 CARVE YOUR NAMES INTO TREE.
 if she`s mad. KiSS her
 give her piggyback rides
 bring her ROSES just because
 treat her the same around your friends as you do when you`re alone
 look her in the eyes & SMILE
 let her take as many pictures as she wants
 SLOW DANCE with her, even if there isn't any music playin
 KISS HER IN THE RAIN.
 if you`re in love with her.. Tell her
Honestly, I don't know that these are the best ideas. How many girls do I know that like being wrestled with? I just can't see that being a common scenario. That's what the "domestic disturbance" calls on Cops really are. And kissing in the rain? How is that different from regular kissing, except that it looks better in movies? And the "as many pictures as she wants" thing. Most girls I know hate having their pictures taken by guys, but it might be a one-way street there. And the whole "Babe" thing. That seems a little demeaning and embarrassing. My clients (I'm talking about insurance fraud scams when I was like 8, not prostitution) always used to hate it when I called them that.
Now some of the other ones make a bit more sense. The slow-dancing, I hear that works pretty well. The smiling... well, you can't have anything but smiling. Talking to her in the park and telling her jokes... yes. Those are the ones I would bet most heavily on. Oh yeah, and telling her you love her. That seems like it would be really obvious, but for some reason it isn't. Stupid world.
Hmmm... seems like throwing pebbles at a window would get you arrested.
So the lesson today is: The internet is either always wrong or it's usually mixed between wrong and right but always very misleading. I think I'll go with the second option. In the above example, there were truths and falsehoods. But if you weren't careful, you might accidentally think it was all right and do something stupid (like beat up your girlfriend thinking that she'll get that you're just "play wrestling").
On the internet, you have to keep your eyes and ears open so that you don't fall into a stupid trap and buy a whole case of Enzyte or download a million virii (look, I know the rest of you call them viruses, but I'm not the rest of you. And I can ignore spellcheck.). Think, man! Don't just act like a robot! Don't just believe what you're told!
