You and your friends are hanging out and there happens to be a guitar in the room. (Acoustic or electric, doesn't matter). They say "Hey, you play guitar right? Play us something!". What do you play?
I think the typical answer would be something strummy that you can sing along with like Wonderwall. But I can't sing. And strumming some chords with no vocals or backing track is very bland. Same with playing just the guitar part of a song that normally has a whole band.
So what can you play that makes an unaccompanied guitar sound good? I'm thinking some kind of fingerstyle solo arrangement like https://www.youtube.com/watch?v=WlGiOiRQNhI (Nothing Else Matters Danish guitar performance - Soren Madsen) would be sure to impress. Any other ideas?
