There've been some funny ad headlines on this site, but this one takes the cake:
 

Like gay movies?
You might be gay. Take the quiz and find out!

I saw one for a Penis Enlargement once.

Yeah, there have been some really wild ones. This one was so funny, though, because they're trying to convince you you might have been wrong about your sexual preference in one line:

You might be gay. Take our quiz and find out!


What the hell is supposed to happen...
"Well I'll be damned...I am gay!"

I saw one the other night that was just gibberish- just random letters and numbers, and it linked to www.com - a non-existant website.

Somebody paid for that!

gay movies?
i wonder which horror movies fall under the "gay" genre.
(link doesnt work.)

I thought the Midget Dating Service ad was pretty funny too.

now that's a fun list to compile. these are the ones that come to mind first.

Tremors - macho cowboys wrestling with giant worm/snakes that burrow through the mud

Interview with the Vampire - men in frock coats sucking each other

The Descent - six chicks entering (and getting lost within) a dark, wet opening in the earth

Frankenstein - a scientist builds the man of his dreams and then tries to destroy him when he won't submit

and of course

The Covenant

I'm sure more will follow...

Yeah, but......Interview with the Vampire really is gay, though!

We can't forget Rocky Horror!

Bride has even more....
