Today I hit a ball out of the park and my expression was "huh? what hapenned? I hit one out of the park, woohoo *jumps around*", I think the only way to hit a ball out of the park is hitting the ball to go really close to either left or right side of the field, I "accidently" hit it to the right side.
I also have added another favourite in Wii Sports, it is tennis. I didn't like it before because I still couldn't understand why my swings weren't making fast balls, coincidently today I watched this 4-way multiplayer Wii tennis game and I noticed how quickly they flicked their arms and I was like "hmmm I gotta try that" because I could perceive that the balls were going quite fast between each seen swing, I tired and it works just awesome hahaha.
