I also wanna troll strangers in the public transport via asking them weird questions. Unlike with first example, I sometimes act on this impulse. I've actually managed to get into troll vs troll battle once when the guy in question asked me whether this was the airport where flying saucers landed while pointing on a gas station, and I responded that no, he was mistaken, because this was obviously a parking spot for submarines. We got into a long, convoluted conversation about umbrellas, aliens and collars for giraffes which was sadly interrupted by me having to leave as the train was approaching my home station. I left with: "Gotta go, my mother ship has arrived for me," and the guy responded with "Bye, you're a pretty cool girl," which inexplicably made my day.
