If FH was filmed with real audience, who did they when 3 michelles appered in "The devil made me to do it" episode? I look at www.tvtome.com/FullHouse but that was not a actress namned for the 3rd michelle. somebody who knows. i clip show scene maybe?

I don't know if the 3rd Michelle was either Mary-Kate or Ashley. The two Michelle's was done by Mary-Kate and Ashley. I have that episode off of WB11 last year (not ABC Family or Nick at Nite).

That part was more than likely not filmed in front of an audience.
