After that stunt, he is most definitely not getting any that night, or probably any other night - at least not from her...
Women don't take practical jokes as well as men, I thought it was pretty damn funny. What's so bad about it? Heaven forbid she has to take another shower.
It would have been funny if it had just been some regular shower - but he said she was getting ready for a party - she had probably planned the schedule to be ready at the right time to go - and another shower would screw that timing up. He is an asshole...
