Table for 26

Alright, listen up, you're not the sharpest tool in the shed, are you? You probably still think the earth is flat. Okay, so the humor in this "joke" is that Jesus asks for a table for 26 when there are only 13 of them. The punchline is that they're all going to sit on the same side which makes it sound like they need more space than they actually do. It's a play on the ridiculous notion of needing that much space, get it? It's funny because it's not logical, like you trying to understand advanced math.
