The title of the episode would be "Guy's Night Out."
The premise is this; Spike starts to feel odd that he's always hanging out with six girls and that he has no guy friends. So he decides to try to get some of the well-known male characters together to hang out.
This would most likely include Big Mac, Discord, and Shining Armor. Maybe Snips and Snails. Maybe Breaburn. Maybe Mr. Cake. Maybe Bulk Biceps. No background ponies like Dr. Whooves. I can't think of anybody else off the top of my head at the moment.
How does that sound?
