Saw this a while ago but can't seem to find it now. It was a YouTube video, seemed like a home video or class project where a girl eats a talking sandwich and inflates. Pretty sure it was called acid trip, does anyone have a link or it saved? Been trying to track it down

This is a clip from the movie. But, I know the scene you are talking about. The whole clip used to be on YouTube, but it was taken down.
