When I'm playing games, I ussaully interpret the voices completely wrong.
Like In Mario Hoops:
-When Mario dunks the ball I thought he said "oh yeah!", but until I read the review, it said "boo yeah!"
-During the character select screen, for I while I thought the theme was "We are... Te-e-e-am" but it really was "3 on... 3"
-When the White Mage finishes her super shot, I THINK she says, "It's too late!"
There were some other things too, like in Warioware Touched, I did not understand a word of Ashley's song until I read the lyrics for it...
...By the way, one time when Mario dies, what is he saying in Super Mario Sunshine? it sounds like, "Vidividechi". Or something weird.
Any of this happens to you?
