Story called you and I (I think).
where someone meets a friend in a bar and turns out has powers to change people and changes the waiter to hulking bodybuilder who comes out of clothes.
cant remember much other details.
a story of when two women are sitting in a libary and by a statue they gain the ability to change there friends/boyfriend with out them knowing it.
Also the same synopsis but two guys in a bar change each other without knowing it.
