Watto: So you are a Jedi? Mmm, I accept the wager. Red, I race and you Jedi become my slaves. Blue, Anakin can race...
Watto: {under breath, to self} and I turn you in for the bounty.

Jar Jar: Uh oh...
Qui-Gon: Hmm. I take a reroll.

GM: We've been rolling dice since the campaign started!
Qui-Gon: Oh, those dice.
Qui-Gon: Cool.
Qui-Gon: That's even more useful!
