My advice to all of these decathlon things is not to try very hard to be serious. In other words, the best entries often make no sense.

I actually tried for the first one. I really did. Then Psy won with something completely irrational. The second one, I tried a little bit less. I tried to imagine a situation in Mario Kart, and tie it with rhymes. Easier than say, doing a limerick on the entire plot of FF7. And now, for the third one, there's so much freedom you can do whatever you want that isn't porn.

Just have fun :D
