Two films opening this week offer the biggest gay week in comic film yet, but it's a joke. And whether you're in on the joke will decide not so much on your sense of humor but more on your cultural leanings.

The two films – as if I need to mention their names – are Sacha Baron Cohen's much-hyped Bruno (Did you catch those clutch gams on the cover of GQ?) and Director Lynn Shelton's bromance film Humpday.

At first blush, these two films have little in common except for their gayness. But unspooled the films reveal their similarities.

In Bruno, Cohen dives head first into the character of an effete stereotype of a gay man. He has great comedic slapstick timing, but the schtick gets old fast.

Bruno, a gay Austrian fashion journalist, travels the world looking for bigots to unmask with his homo tomfoolery. Bigots who inevitably blow a cap at Bruno's over-the-top gay antics. All the while, Bruno remains naively unaware of what's pissing them off.

But believing that such an efficaciously gay creature exists remains difficult to swallow. While Bruno manages to induce some real hate out of his dupes, proving that homophobia lurks just one exaggerated swish away, most viewers will be laughing at his hedonistic homo caricature, not the unease it provokes.

Humpday is farcically similar in its message. In it, two straight men, Ben and Andrew, set out to create a pornographic video on a dare, starring themselves. It's supposed to be the macho version of a gay game of chicken. They climb into bed and … talk, talk, talk. Viewers are more likely to be mumbled to sleep than find the premise believable.

And while straight viewers with a weak stomach will feel queasy at the sight of these gay gags, gay viewers won't get much relief either. That's because the joke in both movies is that sex between two men is inherently funny. (Perhaps Humpday will find a niche following among social conservatives trying to press the point that being gay is a choice.)

Whether you enjoy Humpday or Bruno will likely depend on whether you fall into that narrow strip of simple-minded people willing to accept the premise of these movies, yet are enlightened enough to be in on the joke. Good luck.
