I believe I have found a Easter egg. (See attached images)
It says that every july 4th. Not just 1776.
EDIT: I always knew that, I just never said anything... ;)
Dang, it so happens I never thought to play a 4th of July file (or if I did I didn't notice it!). So I didn't say anything! :D
I think I played one (this years), but never paid attention. Nice! :)
By the way, I think this should be in the Chronom section.
