I really want to use these as a prank or as some sort of punishment for a bet. It's just too absurd.

I'll watch some Dragonball Z in Japanese without subtitles, and when I watch with my friends, they'll ask me "Erik, what did Vegeta's scouter say about his power level???"
I'll scream "It was over 9000!!!!" and as I crush my expensive new translation device, I'll power up and destroy everyone in the room.
