Забавный анекдот. Ошибок в тексте не так уж много, но они есть. Если бы меня попросили их исправить, вот как он выглядел бы:

Michael asked his wife Sharon, “What would you like to get most for your birthday?”
Sharon said, “I’d like to be fifteen again.”
On the morning of Sharon’s birthday, they got up early and ____ went to a theme park. Michael put her on every ride in the park: the Amazing Roller Coaster, the Screaming Loop, the Tunnel of Fear and many others.
Sharon tried every ride in park. She staggered out of the theme park five hours later. Her head was turning and she was having nausea [or: she was feeling nauseous]. Then they went to a movie theater where they ate popcorn and sweets and drank coke. They got really tired. At last they came home and collapsed into bed.
Michael leaned over and asked, “Well, dear, what was it like being fifteen again?” With one eye opened, she groaned, “Actually, honey, I meant the dress size!”
