I thought it was interesting that Marge went to various trainers in different styles of fighting. However, why Mr. Burns?!? I'm sure she could take him on without any problem.
When Mixed Martial Arts mania sweeps Springfield's male population, Marge doesn't get mad, she gets into SNUH mode, and enRAB up cutting a deal with the promoter; the fights will move out of Springfield...if Marge can win an MMA fight between the two of them.
