I was watching some kids play with a 3x3x3 on a packed bus today. One of them had it most of the way but was stumped on the final 3-edge swap. Pretty impressive actually, but he just couldn't get it.
I offered to show him, but managed to flub it - I don't have moves memorized, and rely on RxR'x' to solve the cube, pretty much making it up each time - the antithesis of speed cubing. I haven't touched a cube in several months and was tired and yadda yadda excuses excuses.
So then I had to solve from scratch since I'd mangled it which took my usual 2-3 plodding but meticulous minutes, after which the back half of the bus erupted in applause. (And comments like "I always took the stickers off!".)
I made sure to comment that "I know tons of people online who can do it in 20 seconds reliably. Don't clap for me."
