I am loving Telltale, and love Sam and Max, and every one of these games is a treat but I have to admit I was especially tickled by the inside reference to the original adventure game, Infocom's ZORK at the beginning of Episode 4.
In case you didn't catch it, it was: Here we are in a field west of the white house
Kudos on your clever writing and a great adventure gamer flashback :)
p.s. there was even a mailbox there!
