Fun forum game I thought up a while ago. Just list one per post, and the next person lists the point of it, and a new one.
Example:
Poster 1: What's the point of having a computer without a monitor?
Poster 2: To urge you to get a computer. What's the point of having a rare addon without blockland installed?
Poster 3: To raise your popularity! ...........
And on and on and on.
I'll start:
What's the point of having an erection without a bitch?
