Welcome to Class. I'm Your Teacher, Mr. Danza.

How weird would it be to walk into your first day of English class and see Tony Danza, star of that awesome '80s show "Who's the Boss?" standing up front? Pretty freaking weird, right? And to make things even more odd, giant TV cameras would be sitting in every corner of the classroom.

As is often the the case in SparkLife, truth is stranger than fiction. It seems Mr. Danza is vying for a position as a 10th grade English teacher in a Philadelphia high school as part of a "nonscripted, documentary TV series" (read as REALITY SHOW). Students would have the option of being part of Mr. Danza's class.

In all fairness, Tony could make a really great teacher (after all, his daytime talk show provided guidance and support to millions). And what if this experiment led to a new trend? What if principals and school boards around the country started competing for the hottest celebrity teachers?

We're so glad you asked. Here are our thoughts on how the high school experience would go if certain famous folks took charge of the classroom:

Billy Ray Cyrus (aka Miley's dad): Lessons in chemistry would involve everyone dressing up and performing as a different element. And each class, Monday through Friday, without fail, would conclude with his solo rendition of Achy Breaky Heart.

Paris Hilton: As gym teacher, Paris would spend class instructing students on the cardiovascular benefits of shopping. She'd lead catwalk training and paparazzi posing and might remember to like, ask students if, like, they, like, stretched at the beginning of class.

Simon Cowell/Randy Jackson: This duo would be required to co-teach, as neither would be tolerable alone. They would sign up to lead a music class, but in a crazy, reality show twist, they'd be assigned to an AP Calculus class and would spend the entire period talking about how bloody awwwwful multiple variable functions are and how limits are a bit pitchy dawg. On the plus side, each class would conclude with a classwide vote resulting in one student getting booted out. The end of the semester would see the crowning of Reality Student Champion.

Tina Fey: Judging from her role in Mean Girls, Tina, as her students would call her (cause she's cool like that), would strike the perfect balance between disciplinarian and off-beat kook. She would teach a photography class but would spend the first couple of days trying to figure out how to zoom. That little hang-up wouldn't stop her from imparting lessons about self-confidence and the importance of finding humor in mistakes.

Tyra Banks: Her class would be almost exactly the same as Paris Hilton's, except she'd claim it was totally different and wayyyy more fierce.

Dan Bergstein: All right, so technically, he's not a celebrity, but we know that if you had a choice, you'd sign up for his creative writing class. He'd teach the nuances of satire versus parody and would assign students to research and analyze successful blog posts.

What celeb would you like to have as a teacher? What class would s/he lead? Or can you imagine a worst case scenario for this setup—a celebrity who would make a truly horrible teacher?
