What are the worst opening lines you have ever heard or thought of?

I think of them all the time.

My most recent thought-up one came while reading in this thread about
peeing.
And that thought, in response to the proclamation that "A clean penis is a happy
penis. And a happy penis goes places!"
was.....

1) "I cleaned my penis and I hear that I can now take it places. Can I show you
where I'd like to take it?"

2) "Can you help me clean my penis?"

and 3) "You don't look happy. I want to make you happy. I want to show you
something that is happy and will, hopefully, make you happy..."

Usually my worst pick up lines are not that dirty. They are often more along
the lines of this:
"Hi, I'm doing a study to see if I'm irrestistable to women and I.. Hey, where are you
going? You're going to screw up my --- oh, I get it. Very funny."
