How far can I go? It is a mustery. Damn. Already. Let's pretend that was just a mustard pun. Myustery? Mustery? Get it? Good, we continue. I, uh, make puns often I suppose. Not as often as mistakes. Most certainly. With my backspace broken, this is all unfiltered thought routes. An interesting concept, somewhat. See? I couldn't change that thing there, just like in real life where when you talk, there's no such thing as removing a spoke thing - you must avoid saying it entirely. Unle- nevermind.
2 mistakes, it seems. I mean, 1 mistake and 1 mustard pun. Yeah that was a pun, shut t-- shut it. Okay, two mistra-- three mistakes and one mustard pun.
