My favorite sandwich is a gyro

I'm too lazy to make two separate experiments for Physics (demonstrate precession) and Biology (grow a mould). Any ideas?

My girlfriend broke up with me a month ago and I'm feeling really depressed. She was all I had going for me and she left me for my best friend.

Last night I cut my arm to the bone and just watched the blood pour down my my fingers onto the carpet for almost 20 minutes. I just needed to feel something other then worthlessness and rejection. My mother came upstairs to tell me she was leaving to go to the airport to pick up my dad. I snapped back to reality for a moment and told her "Ok" and "I love you mom". When she left I realized that I could never really kill myself because it would just make my friends and family feel like shit.

How do I deal with this? What should I do about my arm (I havent gone to the hospital yet because i dont want anyone to know)?

If you had to describe Superman as a food... what would it be?

That techie guy from Ducktales, what would say about his sandwich preference?
