Pick-up lines that don't work (usually)

I initially thought this would be better in Laugh's and Games (I guess now named Mom's Basement?), but I reconsidered and put it here. I think that this thread will do better here because if anywhere on GFF, this is where people go who have just been shutdown. If the mods wanna move it, please feel free (like you need my permission).

Post a real pick-up line you've used, or something you've just thought would be funny to say. None of the cheesy off-the-web pick-up lines that everyone's heard already please :\ I thought of this one while getting a Slurpee and seeing a cute girl also getting a Slurpee.

*walks into 7-11 and pulls out a large Slurpee cup*
*sees cute girl getting a Slurpee*
"Hey, we both like Slurpees, wanna fuck?"

Not very creative, I know. On a more realistic (but still humorous) note, I once tried to get a girls number at the bowling alley by saying "Can I touch your bowling ball?"
....
...
"I have a boyfriend..."

Jam it back in, in the dark.
