Go to the scene where Deuce is at the sushi bar. After a few minutes into the scene, he sees the sushi guy about to chop the head off of the little fish. Then the girl he is with asks the sushi guy if he could stop doing that. He says OK. And they are given (or buy) the fish. Then, later in the date, they go to a walkway that ends at the ocean. They then proceed to dump the fish back in the water. If you look closely around the bottom of the screen, right as the fish goes out of the viewing area, you can see the splash from the pot/pan/cup of water the fish is caught in by one of the stage crew members. I know they didn't want to hurt the fish, but they could have put water at the base of the walkway to make it look real. If you look closely, it looks totally fake. You decide!
