What is a good presentation topic?

I need to pick a random topic for my spanish class to talk to my class about for 10 minutes. It can be about anything I just need to talk about it for a decent amount of time. Some examples that people have already done (No repeats):
Favorite TV shows
swimming
water polo
their family members
their favorite class
what they want to be when they grow up
summer vacation
facebook stalking
their job
breakfast
their cat
cake decorating
