i was watching it (an ep that had about 6 or 7 girls left) then all of a sudden they show a commercial with the final three.
UMMMMMMMMMMMMMM HELLLLLO?!?!
MTV also ruined a real world/road rules challenge this way one year. (last year) they had a commercial for the "reuinion" or something like that showing who won 5 minutes before the finale ended.
