BlameThePixel!

I was hanging around in a library and accidently found a book full of riddles. And Star Worms quiz seems fun (greetings to him)so I decided to put them two together. I write a riddle here and you can ask me questions in order to solve the mystery. I only answer "yes" or "no" so that this won't be too easy. When someone finds out the answer, he/she can post it here and write another mystery. If he/she doesn't want to write new one, I'll do it. If you want scoring system, that can be arranged. If there's a mystery posted here you've already heard and know the answer for, don't say it, please. Thanks.

Edit: Oh and using Google isn't fun at all, dont you think?

And here it goes, let's take a short mystery at first. I don't know if it's well known there where you live but anyway:

There was a man with a backpack coming to a hayfield. When he reached the middle area of the field, he died instantly. What happened?

Close enough. He was a parachute jumper and jumped off a plane. Unluckily his parachute didn't open and he fell straight to gorund. bl.

That was solved way too fast.
Wanna post new mystery? Or shall I do it?

Did the middle of the field contain a foutian of cyanide, whereby the fellow thought it was a nice foutian of water so he drunk the cyanide, thus killing him instantly?

Nice theory. But too late. =/ We have good sense of timing. So Star worms, how about it? Wanna post new mystery?

is it suicide?

Ah I think I know this one.

He was talking to someone over the phone, and the guy at the other end spoke the funniest joke ever, you know, the one in the Monty Python sketch!

As a result, he died and before he died he was laughing and banging his fist on the windows, thus breaking it.

Why not?

Serial killar

Yeah, I know this one too Peltzi.

Is attempted murder out of the question?

If not, then:

A guy with a beretta shot at the person in the phone booth, missed and broke the glass with the bullets. Someone came along and stopped the guy with the gun from doing more harm. The guy in the phone booth had a heart attack so he died.
