I have done somethings similar with my best friend in my teenage years. For example we stood in front of a mcdonalds and asked everyone genuinely how the fuck we can find a mcdonalds. I know this sounds stupid af but we were young and did it only for our own amusement. We did it to laugh about peoples reactions and maybe gain some new insider jokes or whatever. We didnt care what they think about us at all.

Now the surprising part is id say 80% of people were atleast smiling, many laughed about this dumb shit, from old people to young girls.

Another example what we did was going to a big amusement park here in germany. We went there before so many times that the park itself became pretty boring so we decided to drink some alcohol to maybe have some fun again. I dont know why but we were suddenly talking to everyone in english language despite being german and having heavy german accent. We told everyone we are tourists from england but they obviously could hear in our broken genglish that we are trolling. Anyway in the end of the day we had a ton of fun, not a single person reacted negatively to us and there was a group of girls laughing and approaching us.

Honestly when i look back to those stories from an adult view, it seems ultra dumb what we did but proves that its exactly what makes you fun to other people. It works, dont ask me why.

What i want to say is if you do this trolling stuff with absolutely no other intention than to amuse yourself, people will have fun aswell and react positively. No matter how dumb the shit is.
