Gay Old Time

Alright, listen up, buttercup. The joke is that the person is giving out a phone number for folks to call if they want to have a "gay old time." "Gay" as in, you know, homosexual fun. Get it? This is funny because people love sex. And you are not too bright because you like this joke. You are probably one of those people that think that adding an exclamation mark to the end of the statement will make them more funny. It does not!
