You shouldn't be allowed to sue over a video this funny -- but alas, someone is.
Sarah Welch -- a model and former contestant on "The Bachelor" -- is suing several companies involved with the fashion show she worked at the Mondrian Hotel in West Hollywood on October 18, 2007.
We found the lawsuit -- filed in Santa Monica earlier this month. Welch claims she suffered "great injuries to her body, shock and injuries to her nervous system" after she fell through a hole in the runway which was created by the performer who went on before her.
Welch is suing for negligence and is seeking unspecified damages.
