As for HtR easter eggs, I don't know if this is one, but please tell me you've tryed constantly picking up an object and heard all of sam's lines. Especially the last one. Hillarious!

Sam: Oh I give up
Max: Oh now you done it! You've spoiled Sam's sense of (I don't remember what it was) with your attempts to pick up that stupid object
Max: In fact if I didn't find his pityful sobbing so amusing, I'd go out there and rip your limbs off.
Oh and have you guys actually tried putting money in the well at Bumpusville(twice!)
