With whom do you share a birthday?

[Angrboda]

If I ever wanted to end a date quickly, I think excitedly mentioning that I share a birthday with Squeaky Fromme would work.  Except I'd get the ones who didn't know who that was.

I certainly have no idea who that is. xD
Looked it up, though.

Yeah, but you're young enough to have missed that bit of history. I'm less likely to be dating someone that young. And if I am, I would appeal to other deal stoppers.
