Okay, okay, so they never tell you this in Christmas time, but Santa and his old lady totally had conjoined twins as kids.
Now, Santa and the missus, they’re cool people right, they want to do right by their kids, but they totally weren’t prepared for this. So they do what a lot of folks do, right, and they talk to the doctor about what the right thing is to do for their kids. Should they be separated? CAN they?
And the doctor says no, they share a digestive tract, there’s no way the kids could be safely separated. Much better that they live as they are, since they seem pretty okay, just different. They’ll be all right, because after all: a semicolon can be used between two closely related independent Clauses.
