Hulk: The name's Hulk Hogan! But my friends call me Hulkster.
Skeletor: Well then Hulk Hogan, what the hell are you bothering me for?
Hulk: I'm here because I heard you were down, and I thought I could help! Just like I'd help any of my Hulkamaniacs who were in trouble!
Skeletor: ... Don?t even look at me. I'm hideous, and a loser to boot.
Hulk: I don't want to hear it, rotting dude! I know if you believe in yourself you can succeed. You just have to train, say your prayers and eat your vitamins, brother!
Skeletor: Why do you want to help me?
Hulk: Look at me, brother, I'm almost as much of a skeleton as you are! Can you see the crevices in my cheeks? After all the vitamins I took back in the day, you'd think that I'd be healthier, but the doctor tells me that those particular vitamins actually caused a lot of problems. I thought it was strange that I had to inject them. Usually you just swallow them at breakfast or something.
Skeletor: Well you learn something new every day. Do you really think I can defeat He-Man?
Hulk: I know it, brother. Just let me train you.
Hulk: Off to train, dude!
Skeletor: Uh... right.
So the Hulkster took Skeletor under his wing, and began his intensive training.
