Vegeta: I'm going to go and put myself under. Need to find a room to do it in though.
Goku: Why would you do that?
Vegeta: Because Kakarot, for almost a year I ran off of ten minutes of sleep. The other day I was asleep all day. Now I'm going to get a few more hours of rest.
Goku: Wow, you must be busy.... No wonder you're grumpy!
