Boyfriend: My Siamese twin is weird.
Me: ... *edge away*
Boyfriend's brother: ... What?
Boyfriend: It could be a quantum Siamese twin, you know, it only exists when no one is looking... though I suppose the proper term would be conjoined quantum.
Me: ... *stare*
Boyfriend's brother: *can't breathe*
Boyfriend: Hey, what country used to be Siam?
Me: Thailand, I think?
Boyfriend: That's a hell of a jump to b known for... from twins to underage prostitutes... *grins* My Siamese twin is an underage prostitute!
Boyfriend's brother: *DIES*
