"I wanna bag you like some groceries."
I found this and other funny pick up lines at this cheesy pickup lines site. I think its a new site as it looks like it hasn't been totally finished yet. Have you tried this one:
"I know I’m not a grocery item but I can tell when you’re checking me out."
I've often wondered if pick up lines really work? If you are the ugliest guy in the bar then any fancy pick up line isn't going help you to seduce ladies. Well at least most of the pick up lines are quite funny.
