When George is in Rudy's and Rudy says that when moth larvae hatch they are everywhere, he and George stand next to each other; when the camera angle changes, George is on the other side of the shop and Rudy is behind the counter.
There have been beltless trenchcoats since there have been trenchcoats and they are still being made.
George says that a paella is seafood, meat, and rice. No self-respecting Spaniard would ever mix seafood and meat together in a paella. A traditional paella is pure seafood and rice. A meat paella is a twist on the traditional paella, but it never contains seafood.
At Rudy's Antique Boutique, he explains to George about the moth-ridden cabana clothes he sold to him: "All it takes is one moth to lay eggs. You know what happens to the larvae? They hatch and they're everywhere." Larvae don't hatch. Eggs hatch, and the larvae molt.
Kramer said he'd take care of everything with the trenchcoats so it wouldn't matter if they arrived after Morty left.
