How do you ask out a gay guy?

Same as anyone else: "Hey, do you want to catch dinner and movie with me one night this weekend?" "Hey, do you want to go see a ball game/show/rodeo/play with me this weekend, I have tickets?" "Hey, do you want to grab a cup of coffee with me on Saturday afternoon and then go check out the farmer's market?" Etc.
Hey man, you wanna go get a bite to eat?
