This episode is just pure garbage in my book. And I am not usually harsh, but this time I can't disagree more with the general view.
Funny? Not at all. That would be a nice pretext to enjoy this episode despite being so chaotic and pointless, but I actually laughed twice. And neither of those laughs were too remarkable to compare with the jokes at older episodes.
And, while the episode couldn't satisfy my demands in humour, it got worse and worse in plot and characterization. The storyline went nowhere and Homer was depicted here as a menacing psychopath that could have killed himself without remorse. I'm sorry my opinion is so conflicting in this occasion, but this is not the funny, lovely Homer I met. And I'm especially sensitive to the characters' depiction and everything related to empathy.
So, terrible show at all, and proud member of my bottom 5. The intestinal strip-tease did the rest.
