The Eleventh of May. A day of celebration for teenagers of English, Dutch, or Swedish, decent across the U.S. but primarily in Southern California.
Nathanael: "Don't forget about May 11th."
Wesley: "I couldn't possibly, you've only told me like a hundred times."
Nathanael: "Haha."
Wesley: "Don't worry about it, dude. It is Once De Mayo after all. We're totally gonna party."
