"Get weighed" joke

edJoe took his blonde blind date to a seaside carnival.
'What would you like to do first, Kim?' asked Joe.
'I want to get weighed,' she said.
They ambled over to the weight guesser, who guessed 70 kg. Kim got on the scale and it read 67 kg and she won a prize. .
Next the couple went on the ferris wheel. When the ride was over,
Joe again asked Kim what she wanted to do next.
'I want to get weighed,' she said.
Back to the weight guesser they went and because she'd been there before the man guessed Kim's correct weight and Joe lost his dollar.
Kim and Joe walked around the carnival and again he asked,
'Where to next?'
Kim responded: 'I want to get weighed,' but by this time Joe figured she was really weird and took her home early, dropping her off with a handshake.
Her flatmate, Laura, asked Kim about her blind date, 'How'd it go?' she asked.
Kim said, 'Oh, Waura, it was wousy.'
