It took me a minute to suss it. duh!
A girl goes out on a blind date and the guy takes her to the State Fair. They go on some rides he buys her a hot dog then asks her what she’d like to do next. “I wanna get weighed.” she says, so he takes her to the arcade, puts her on the scale and it says 128 pounds. They go to the fun house, play some games and he buys her some cotton candy. “What do you want to do now?” he asks. “I wanna get weighed.” she says, so he takes her back to the arcade, puts her on the scale and it still says 128 pounds. This goes on for hours. When the girl gets home her mother asks her how her blind date was and the girl says: “Wousy. Weally wousy!”.
