Here's a fun and exciting challenge that's sure to have people hanging their own grandmothers on meat hooks just for the privilege of entering. In fact, if you want to show people hanging on meat hooks, including your grandmother, that's perfectly "rules-compliant."
Your mission, which I predict will have you pinching yourself in joyful disbelief for at least a week, is to depict normally serious people doing funny and/or stupid things. Take some really, really serious person or persons, living or dead, and stupid 'em up.
Maybe they've chosen a different career path -- maybe they've gone totally insane. Just make them look so uncharacteristically silly that whoever looks at your entry will be inclined toward the involuntary emission of a series of bark-like yelps, or perhaps even an abrupt "chuckly" noise.
Why are you still reading this? You should already be working on your entry, which will be judged harshly and with no mercy, just as you yourself will be judged as a person, found guilty, and then summarily terminated. Terminated -- with extreme prejudice. There will be no exceptions.
Legend, oh legend, the third wheel legend...always in the way.
