Well I got three options, all with various levels of "coolness":
1. I could say, "So long, and thanks for all the fish.", but Ms. Alba and Mr. Bus wouldn't even recognize the reference, so what's the point...
2. I could say "Hello. My name is Inigo Montoya. You killed my father. Prepare to die.", and then proceed to run the bus through with my rapier...but Ms. Alba and Mr. Bus wouldn't even recognize the reference, so what's the point...
or
3. I could yell "This is SPARTA!" And proceed to kick the bus into a bottomless-pit, but feel dirty for having to resort to an obvious and tired phrase that does in fact get old after awhile. So what's the point?
Toss up, really...
