A plane crashes on a desert island and the only two survivors are Steve and Scarlett Johansson.
After many long lonely nights together on the island they fall deeply in love and start having the best time together but Scarlett notices a deep sadness in Steve's eyes.
She tries talking to him about it but he cannot bring himself to talk about it.
Months go by and Scarlett sits down at the fire and explains to Steve that she has never loved anyone more than him and is desperate to make him happy.
With some trepidation Steve asks Scarlett if she can wear an old shirt and shorts that he's found and draw on a moustache with charcoal from the fire.
Scarlet leaves camp one night, gets dressed in the ragged salt stained clothes and draws on the fake facial hair and then walks back towards the camp fire.
Steve's face instantly lights up as she enters the clearing, he jumps up from his seat and runs over to her "Dude! You'll never guess who I've been having sex with!!!"
