Don't you just hate it when you're a long-distance bus driver in Chile and you accidentally forget that hardcore porn you were enjoying earlier in the coach's video tray and then press play thinking it's You've Got Mail or something and then passengers start giggling and you have no idea why until some spoilsport points it out to you and you're embarrassed as shit?
This guy knows what I'm talking about.
