I’m pretty sure I heard it here first - gay as 19 balloons. It’s still my favourite.
Yes, true dat. Plus, he said “Gay as a King” but stopped short of adding “Gay as a Queen.” Had he added that, I would have forgiven the whole glurge infused post.
I like “Gayer than Gay Gayerson”
One day, my SO finally asked me—“Who is Gay Gayerson?”
As far as I remember that line is from the episode of Roseanne where Martin Mull’s character is getting married to his boyfriend and he has massive cold feet. She’s trying to calm him down and he’s going on “Maybe I’m not even gay! I mean, I like sports! I–”
she stops him: “Do you like to have sex with men?”
Him: “Well, yes…but…”
Her: “GAY!!! Gayer than Gay Gayerson!”
That was a great show.

Dude’s as gay as a pink flamingo. What, you mean flamingos aren’t all gay? Damn, they sure are pink!

Gay as Christmas
LOVE IT! Stealing it.
On a related note, I’ve always liked “He’s so far in the closet he’s eating turkish delight with the witch queen of Narnia”.
Now THAT made me laugh out loud!

Gayer than Richard Simmons running naked through a field of pussywillows.
He took longer to leave than Michael Jackson at a Cub Scout meeting.

I really hate to admit this, but I am not getting a lot of these at all. For example, french horn. And all of these.
A lot of the ones in this thread are pretty obvious (and I think the subtle ones are funnier) but these are just so out there I don’t get it. Will I spoil the thread if I have to ask?
