First, gay people will get married
...then gay dogs are going to get married
Cats will think gay dog weddings are rad and they'll start being gay
The sun is probably going to get all gay with another sun
But then the moon is going to get the wrong impression and try to move in with us
Which of course will lead to the first of many Apocalypses
Sensing weakness in the human race, Gorillas will finally overthrow us
They will force us to exclusively produce movies starring Brendan Fraser. OH THE HUMANITY
If you let gay people marry each other, your kids will grow up to be timeshare salesmen... and they'll have bees instead of fingers
