This happened just last week when I was walking from my car into work in my little waiting uniform.

"Ooooh baby, you are makin my heart buuuuurn!"

I walked inside and said to the bartender:
"You know, I always thought heartburn was a BAD thing!"

Let's see though, cheesy lines I've used recently on my boyfriend for a laff:
(said in little girl lost voice) I dwopped my lollypop, do you have anything I can suck on?
I have an oral fixation, do you have anything I can put in my mouth?
It's too bad you have a thing about handcuffs, cause I'd like to handcuff you to a bed and lick you all over for hours.

One I heard on tv recently:
After tonight you will be walking sideways for the rest of your life, because I will have used ALL your up and down.
Or, my new favorite from Ally:
I contract just LOOKING at you.

Thanks for all the suggestions! We're both actors and there's a point in the show we're doing on stage when I lean in and whisper in his ear. Won't he be surprised to hear all these great lines?
