Have you ever?

I personally don't. But at work, my colleagues like to tease the dog of my boss a lot. I even have a picture of someone throwing the tennisball (he loves that) against a glass door with the dog on the other side trying to catch the ball time after time.

Have you ever had that your phone was almost out of battery and the cable to charge it was somewhere else, so you thought about bringing the phone to that place just to find out that the cable wasn't there? (or with any other device)

No. Sometimes it happens to my brother with his tablet.
Have you ever been running around in some KS level just to listen music ?

I really liked the music that plays during a certain part of Teenhmifnoeafgil. What i did instead of what you just said is i looked up that screen to find the song's number, converted the song to MP3, and put it in my music folder.
By the way, i'm talking about a custom one "replacing" ambience #241.

Have you ever deliberately looked up a Youtube troll to laugh at their logic fails?

No.
Have you ever been to cinema to watch black and white film ?

I don't think so... I don't go out to the movies much, and I hardly ever go to revival houses, which is where you're most likely to see black & white movies. I think the closest I've come to that were Sky Captain and the World of Tomorrow, which was going for a blurry early technicolor look, and Hugo, which had a couple of b&w sequences.

Speaking of movies, have you ever really liked a film which almost everybody else hated, or vice versa?

Yes. In fact, I've begun to feel like that is my opinion the majority of the time. It makes me think my tastes are not particularly useful to others.

Have you ever watched more than three feature-length films in a row?

No. Once I've watched original SW trilogy in one day.
Have you ever try to grow any carnivorous plant ?

I had a Venus flytrap when I was like four. I'm pretty sure my mom did all the caring for it, though, so maybe that doesn't count.

Have you ever rolled your own sushi?

Sure have! I used one of these, though, so it's debatable whether it counts.

Have you ever made your own pasta?

Yes, but I was really little and don't remember. Does helping someone count?

Have you ever seen the inside of a hard drive?

Yes. Often enough. As a network-/system administrator, we occasionally run into bad disks that the computer has trouble recognize. They contain data from our clients. In order to make sure no one will be able to get data from the disks, we wipe them. If the disk cannot be recognized by our computers, we will open up the disks, take out the writing disks and use a knife to cut it to pieces. (we collect the magnets too. They're really nice).

Have you ever seen a very attractive boy/girl (the opposite sexes) as you were walking/biking/whatever and bumped hard into something? (if so, did s/he or anyone notice?)

No, because I think I didn't see attractive person at all yet. (I mean in common life)

Have you ever cooked something unusual or inedible?

Yes, Chocolate strawberry deluxe!   

Have you ever been been really scared? (If so what was is?)

I've been afraid of many things throughout my life, but none compared to the concept of death itself.  And before anyone thinks the usual thoughts, I am referring to death as it truly is.  The ultimate and final end to life.  Not just mine, but all life everywhere.  I've spent the last 5 years wrestling with the fear, and I don't think I'll ever truly get over it.

Have you ever been in the news?

No. My grandmother was once in the new, where she was protesting against a building of shopping center near her house and my father was once in some TV programme about science where he was talking about his work (it is something with electrons but that's all I know about it).
Have you ever heard you favourite song in a radio, started dancing and singing, and when it ended, you realized that somebody was looking at you all the time ?
