Wow! Have I got some funny stuff for you today! I'm actually still laughing as I type this. Allow me to explain... Normally, our scripts are written with the dialogue in the center of the page and the action descriptions aligned to the left. (Check this post out for reference: Tales From the Script) For some reason, somebody made a word-processing error and centered the descriptive text rather than leaving it left aligned. When the actor playing Yam Roll stepped into the booth with his script he read off his lines as he had always done. The people in the recording booth couldn't figure out what he was reading but once they pieced together that the typing error had been made, they decided to keep the lines in the show because it was just so freakin funny!

The part in question begins a little after 2:45 into the clip. The first line that's out of place is "They swoop off!" Man, that's funny!!
