Hey guys this is just something I kinda noticed after surfing through the forums I thought i'd share what I found at least somewhat fascinating.
So first off we know there's a debate going on of what the bus driver said(link below). Well I think he said "Wear the(or a) mask".
Then second is one of those "leaked" achievements which is called "Tower of babble" which states "obey the voices".
So I'm thinking that it might be a reference to a EE where you probably have to do stuff that the bus driver says.
So feel free to discuss, like I said its just something I noticed I could be entirely wrong.

Link to achievement (sorry I can't find a link to the actuall achievements but here's a link to a thread which the achievement is told by "xMisfitxx" ask him if you want for proof":http://community.callofduty.com/message/413389339#413389339.
Ps. These are iPhone links so I don't know if it'll work for everybody.
? really.. it says "welcome aboard" as in welcome aboard the bus, ..i dont think theres any doubt about that but i hold my hands up if im wrong.
