"Whenever I end up in the courtroom, I get all sweaty and nervous. I can't feel my fingers. I'm very glad I'm not pointing and saying 'objection' all the time, as that's all my colleague would do. But y'know... I'll take the case anyway."

"Enough said." Bobert raised his hand in the air, to which you raise a brow at.

He punches his open hand, weakly, of course, and then...

The hand falls. SA-LAP!

"You ain't got nothin'."

YOU DON'T TAKE THE CASE. You're WRONG, Mr. Wrong. No... Arizona Wrong.
