I've had a few of these saved for quite some time and it is way past due for an update.
"I was the voice of Butters. Had to go to town to give a speech on birth control.
"Had to stop for grilled cheese sandwiches first. They were made out of noodles... I wasn't even hungry."
"I'm done."
"Did you get the ribbon?!"
"Frog stickies, you know what I mean."
Aside from these, I haven't heard any good rambles. Quite the disappointment, I know.
