Gay jokes in fiction usually amount to this formula: one character says something that can also be interpreted as incredibly gay without realizing it and everyone looks shocked at him. The humour comes from the fact that this often happens in real life due to how far down the gutter our minds have gotten (everything can be construed as gay innuendo these days) and that these jokes in fiction capture those isolated moments of hilarity. The problem is they usually aren’t funny because of the fakeness of it all. It just comes off as manufactured and forced most of the time and the humour dies as a result. Every other sentence out of Alan Harper’s mouth on Two and a Half Men these days is a gay double entendre and it fails to crack even a grin from me. Yes, jokes like that tend to have no effect, except of course in the case of Arrested Development’s Tobias Fünke.
