Two friends are hanging out at a restaurant in 2016; one friend has light skin and the other has dark skin. One of the friends has a tattoo that says "time" the other has a tattoo that says "machine". Over in the corner at the bar there's a black hole. After getting drunk, the two friends mistakenly enter the black hole and end up in the same place but in the 1900s. They still look the same and they're still friends.
