When I went back to Canada recently, we had to chip ice off the drive. I was using an axe, and I found out if I hit the ice right, as well as not too near the edge, it'd go THWOK and a huge chunk would come off =D
Other than that, when I'm playing TF2 as sniper and (with my crappy skills) I actually get a headshot, and it goes ptcheeeww (although technically i use the huntsman now so I hear the crit sound later). It's only satisfying because it's like doing major damage with the click of a mouse =)
