Stan Possible Script

flash of light in a room somwhere
mauybe a dorm, doesn't matter
STAN falls to the ground
he's panting
He looks at his phone and compares it to the clock on the wall
his phone is 10 minutes ahead
he runs out of the room
he spends the next 3 minutes running frantically
through a cafeteria, dorm
just pick a path across campus and think of all the funny things that might happen along the way
that would impede his progress
elavator, etc
at the end
he reaches himself
and stops him from making a stupid mistake
and says "don't do it. I came back in time to stop us from making this terrible mistake"
and the regular (not time travelly one) says "but wait. You came back in time to stop me from doing this. But what happens now that I'm not going to do it in the first place.
time traveller (panicked face) "o shi-"
flash of light an he disappears
he collapses inwards
the whole screen uses some kind of folding transistion onto the credits
whatever sort of effect you can slap together
it's nice because, narratively, you only need to come up with one thing

it's nice because, narratively, you only need to come up with one thing
that one mistake
and there's like 3 lines of dialog
all the running scenes are mostly interchangeable

What we still need is several entertaining snags one would run into trying to cross Tech's campus. Any ideas?
