I thought this episode was great,and to the*Simpson's isn't as good as it use to*people,get lost!
21 March 2011 | by (Ireland) – See all my reviews

Donnie Fatso is a great Simpsons episode,with a great Mob theme.Now to the people that always say the Simpsons isn't as god as it was.Get over it and stop complaining about it if you think that its not good just watch some other crap shows that are on these days and you'll thank god we have The Simpsons,the show obviously is doing something good if its been on the air for more than 20 years.A lot of people were complaining about the Fit Tony thing,this is never gonna be mentioned again it will just be Fat Tony,his death wont be mentioned or neither will his cousin it will be like Fat Tony never died,just like the episode where Principal Skinner turns out to be an impostor.

After Homer gets sent to jail for ten years,he works for the FBI to catch Fat Tony,but Homer starts to become friends with Fat Tony and feels bad about what he is doing.
