I'm literally just 27 rats writing this. Rats are very good at delivering packages. Rats can move at max speeds of 500mph. They are the second fastest animal on the planet behind the zoomy cat. Rats know everything so you should watch your back. Anyone who likes Ratatouille will be spared.
That kid is just 27 rats in a trenchcoat. They may kill you if you took their fedora.

Naturally still disgusted by the earwax left on his penis, he then proceeds to wipe the brown sticky material above the load he just blew, creating what appears similar to a black man wearing a white trench coat.
Ford: I totally freaked out when I saw the earwax on my dick man.
Sam: What did you do?
Ford: I had to give him a Seattle Salsbury Trenchcoat dude.
Sam: Him?
Ford:...
