Conjoined Twins

If one commits a crime do they both go to jail? What if one is dates a male and the other dates a female? How many seats do they buy on a plane? Can they read the thoughts in one another's brain? With eight limbs are they an octopus by definition? At the movies do they pay 2 admissions? If they share a butt who decides when to Poo? If one of them dies does the other die too? If one gets pregnant are they both the kid's mom? Will they ever find two dates for the prom? What If one gets into college and the other does not? What happens if just one wants to tie the knot? Do they need one passport or two? If one wants to have sex what does the other one do? Do they both get paralyzed if they share the same spine? Do they both get drunk if just one drinks wine?
