pick-up lines that don't work on me

"Yeah, I only have a forty per cent chance of even surviving the operation."
I mean, maybe if it had actually been true (and as I found out from mutual acquaintances, it is not), it might've got some kind of sympathy fuck vote.
My instincts are pretty trustworthy, though. As it turned out, this same person also eventually mentioned how he didn't like Jews.
"They're greedy; there's just something about them I don't like."
I was too flabbergasted to say anything, and later I felt guilty about that.
Next time I bump into him, though, watch out...

NB I don't plan on ridiculing him; I plan on re-educating him. That's a lot more constructive, I reckon.
