Well, how about your tag.."I can fart with my back" that must really reel them in
Does this line go along with "Did you just fart? Because you blew me away!"
and on the same theme, but less classy (if that term can be used at all) :
"Do you mind if I stand next to you until it's safe over there, where I just farted?"
I first saw the "only ten I see" line in Donnesbury, probably way back during the 1980s.
A few more choice lines which should earn you at least some groans, maybe even a slap (but I doubt if anyone would fall for them):
I play the field, and it looks like I just hit a home run with you.
Was that an earthquake or did you just rock my world?
I may not be a genie but I can make your dreams come true.
(and another version: )
Well, here I am. What were your other two wishes?
Are you a magnet? Because I'm attracted to you.
You are like a student and I am like a math book. You solve all my problems.
So there you are! I've been looking all over for you, the woman / man of my dreams!
If I were to ask you for sex, would your answer be the same as the answer to this question?
Can I take a picture of you, so I can show Santa just what I want for Christmas?
Do you have any raisins? No? How about a date?
I was blinded by your beauty so I'm going to need your name and number for insurance reasons.
I know I don't have a chance, but I just wanted to hear an angel talk.
Hey I just realized this, but you look a lot like my next girlfriend.
(or another version: )
You look like my first wife! (how many have you had?) none.
Are your legs tired? Because you've been running through my mind all day long.
I hope you know CPR, because you take my breath away.
Stand still so I can pick you up!
Are you an interior decorator? When I saw you the room became beautiful.
Is that top felt? [No] Would you like it to be?
Apart from being sexy, what do you do for a living?
I'm invisible. [Really?] Can you see me? [Yes] How about tomorrow night?
I have never had a dream come true until the day that I met you.
If I could rearrange the alphabet, I'd put U and I together.
Turn to the girl sitting next to you at the bar and say... "I'm not really this tall ... I'm sitting on my wallet."
If beauty were sunlight, you'd shine from a million light-years away.
I hope there's a fireman around, cause you're smokin'!
Excuse me, I think you have something in your eye. Nope, it's just a sparkle.
You've been a bad girl/boy. Go to my room.
If beauty were time, you'd be an eternity.
Hi, I just wanted to give you the satisfaction of turning me down; go ahead say no.
I hope your day is as radiant as your smile.
You make me melt like hot fudge on a sundae.
You know what? Your eyes are the same color as my Porsche.
Hi, I'm Mr. Right. Someone said you were looking for me.
Giant polar bear (What?) It's an icebreaker. Hi, my name is....
If looks could kill you would be a weapon of mass destruction.
I don't know if you're beautiful or not, I haven't gotten past your eyes yet.
What does it feel like to be the most beautiful girl in this room?
And finally, if you see a mother and beautiful daughter together, turn to the mother and say, "Oh, I would love to be your son-in-law!"
Why show all my good cards on the first date? 
Actually, I hid it in the foot care section.
