It was hard to pick my favourites from this helpful resource, but these are some highlights:

You're the only girl I love now... but in ten years, I'll love another girl. She'll call you 'Mommy.'
Do you live in a corn field, cause I'm stalking you.
You shouldn't wear makeup. It's messing with perfection!
Put down that cupake... you're sweet enough already.
Excuse me, but does this smell like chloroform to you?
Are your parents retarded, 'cause you sure are special.
I have had a really bad day and it always makes me feel better to see a pretty girl smile. So, would you smile for me?

You're welcome.
