Stick in the mud

"Why the heck are you being such a sour puss, Greg? We've got these hot bodies; we don't have to pay for drinks, because guys are buying them for us; and plus, if we want to see boobs, we can just go into the bathroom and rip our tops off!" Marty told his friend.

"It just doesn't feel right," Mumbled Greg, "I mean, you just used that body switcher on those four women without their permission! Heck, you didn't ask any of us either! You just assumed! Maybe some of us didn't want to be women!"

"Stop being such a stick in the mud and try to have a good time, man!"
