Shortest Heel/Face Turns?

With Elias going back to heel again recently, what was the shortest heel or face turn that wasn't a ruse on the part of a wrestler?  The shortest face turn I can remember was Big Bossman in the Summer of 1999.  The Corporate Ministry beat him down and kicked him out of their group, and he even fought with the babyfaces against them to end the show.  The very next week he re-joined them again, well, because Russo.  Were there any shorter than that?  

Chyna would seemingly turn back and forth through the course of one show in 99.
