You're so beautiful; your birthday should be a national holiday.
My buddies bet me that I wouldn't be able to start a conversation with the most beautiful girl in the bar. Wanna buy some drinks with their money?
Can I have directions? [To where?] To your heart.
I'm no Fred Flintstone, but I can still make your bed rock.
What does it feel like to be the most beautiful girl in this room?
I put the STD in STUD. All I need is U.
I was so enchanted by your beauty that I ran into that wall over there. So I'm going to need your name and number for insurance purposes.
Are you accepting applications for your fan club?
Pinch me. "Why?" You're so fine I must be dreaming.
You're so sweet, you'd put Hershey's out of business.
