HAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHA. . . etc. (And the Laughs Just Keep On Comin')

I related this scene from a Monkees episode to a friend on the phone last night, and I literally began crying and going into hysterics. I was so worked up over it, I could hardly talk towards the end. That's right folks--I think this scene is SO FUNNY, I can hardly breathe when I even THINK of it.
Here is a paraphrase of it:

Monkees: With the phone not working and the fog blocking us in, how will we ever get a message out of this haunted mansion?
Mike: I'll attract a passenger pigeon. Then I can attach a message to it.
(Goes to the open window and places bread crumbs on the sill.)
Micky: I'll believe it when I see it.
(A pigeon lands and Mike picks it up.)
Micky: I believe it.
Mike: OK, now all I have to do is attach a message somewhere. . . .Oh, there's already a message on it. It says: I AM NOT A PASSENGER PIGEON. PLEASE DO NOT ATTACH A MESSAGE. OK. . . .
(He leaves and comes back placing bones in a line leading to the bedroom.
Micky: Where'd you get all the bones?
Mike: I found them in a closet. I figure they might attract a St. Bernard and I can put a message on it.
Micky: I'll believe it when I see it.
(A St. Bernard prances in and stops before Mike.)
Micky: I believe it.
Mike: OK, now all I have to do is attach a message to its neck, and. . . . oh, there's already a message around its neck. It says: THERE IS A MESSAGE FOR YOU ON THE PIGEON.

OK y'all, to be perfectly honest, I'm laughing out of control even as I type this so adios! I need some rest.
PS I fully understand that while amusing, this scene is nowhere near as hilarious to others as it is to me.
PPS Keep in mind its mainly the way Mike says these things that's so funny.
