Subtember 11th 

A relatively insensitive Subway ad released on September 11th. Describes a deal that's pretty damn good though, if you ask me. Two footlong subs for $9.11. You'll "never forget" this deal!
Fly in for Subtember 11th at your local Subway!
Hey Joe, it's Subtember 11th! Lets go eat these delicious, cheap subs in remembrance of the greatest attack on American soil, TOTALLY committed by Al-Qaeda.
