 == 1st goof == 

 Is this really a goof: ""Although Homer stopped being homophobic in Homer's Phobia and even lived together with two openly homosexual men in Three Gays of the Condo he still can be seen holding a sign ""Death before gay marriage""."" 
 I think it's just a sight-gag and a play on Homer's stupidity, rather than a goof.  "
