What is a good argumentative, not TOO serious, topic for a 2 or 3 page essay?

I need a argumentative topic that I write about for english class! This is part of what my teacher gave me:

“This essay asks you to take make an argument, talk about something that means a lot to you (students shouldn’t be treated like prisoners, people should think more about how they treat the environment, vegetarians are annoying to me) and back it up with experiences you’ve had (the time when a teacher yelled at me, the time when I saw someone dump oil on a blackberry bush, the time when a vegetarian gave me stink eye for munching on a Krusty Burger).

The major aspect of your writing I want to emphasize is showing versus telling. Always be wary of your writing when you say something like The party was awesome. Look for places to insert specific, concrete details that can be touched or set on fire or show through a cannon. At the party, Joe kept exposing his bellybutton and slapping his jiggly paunch with his yellow cowboy hat. Moreover, I’m looking for you, who you are, so take a few risks and show me. Remember O’Brien’s advice about infusing your writing with elements of imagination and story.”

It can be funny, serious, or in-between, any ideas will help! (I dont want anything TOO serious though….)

Thansk!
