I can't say I was too impressed with this one. But like the other episodes from this season, this one had its moments. I got some laughs out of Moe getting pounded to a charming railroad song, Nelson's lamb fandom, and the seemingly-indestructible reporter guy.
Other than that, this was a clunker. The opening bored me and the B-plot with Bart, Lisa, and Larry the Lamb didn't do anything for me.
I fiesta on Cinco de Mayo, have some paczki on Casmir Pulaski Day, and get hammered both on St. Patrick's Day and during Octoberfest. It's a feature, not a bug. We're a nation of immigrants, the great melting pot.
