Hey there, I thought I'd post an April Fools video I uploaded just 22 hours ago which already has 4,022 views on YouTube. Basically I walk around on the street and attempt to list the names of 10 operating systems to random people I find in general conversations without them noticing. For example part of a sentence might be "I'm looking for a place called Ubuntu and its apparently near the Linux mint shop" or even "I took a wrong turn at the Android statue so I might need to backtrack" and "I thought this was a good plan 9 minutes ago but I might need to DOS it"
Here's the video:
I hope you enjoy it 
Note that I did this on april fools day and that last guy had been pranked by people a few times so he was onto me...
