Anyway the best way to ask a girl out, is to walk up, hit her over the head with a club, then drag her by the ha- wait.. that's how my dad did it.
In the modern day and age, you gotta be suave, or completely retarted, to ask somebody out.
first the sauveness (It's actually horrible because I'm just pulling this out of my ass)
"I noticed you like cats, I like cats too, meow."
"I couldn't help but ask you, where's the hole in heaven? And when can I come with you?"
(Wait these are gay picup lines...)
"I find you really attractive, and I'd like to get to know you better than a friend. Would you go out with me?"
Ok now for the retarted things
Grin like your pinching out a huge crap, and say "Your pretty, would you go out with me?"
Sometimes acting like a total retard/dork/nerd is so cute they say yes. If your a hardcore rappah you might want to use:
"Wizzle yoizzle goizzle outizzle withizzle m'nizzle?"
Or something like that.
