I completely forgot I had this clip lying around my HD for months...

Unfortunately, I couldn't record the events leading to the glitch since I didn't expect it and couldn't reproduce it. This glitch occurs when you pause the game at a very specific frame at the end of the last round of musical chairs and load a save file. What'll happen is that the game will not only load the save file, but it will simultaneously attempt to play the cutscene after musical chairs.

This comes with a lot of funny side effects, such as Travis not moving correctly, the cutscene interfering with the gameplay, but not hindering you from interacting with different objects, etc. I guess you could cause a heckload more havoc by loading different saves from different locations, loading completely different areas and so on. The glitch basically ends once the cutscene is over and you load a new area or cutscene, but who knows what else can happen? Maybe you can even screw around with other cutscenes if it's possible to enter the menu right before them.
