What would happen if a super klutz (someone who can't even walk across a flat empty floor without tripping multiple times) accidentally (of course, he/she is a klutz!) triggered an experimental time travel device sending them into the past?
I could see multiple versions of this:
-humorous where the accidents caused by the klutz just cause a lot of confusion and mayhem (and laughs for the readers) but doesn't affect history
-serious version A - where the accidents DO change history in some fashion, possibly even a major event
-serious version B - where the accidents DON'T change history because they are actually NECESSARY for the historical events to occur (in other words, the present time period that the klutz traveled from only came about due to the presence of the klutz in the past and his/her actions/accidents there). In this version, the klutz sees that their lifetime of klutziness could have actually been by a grand design/fate instead of a curse.
