The point of that particular flavor of joke is the build up. HUGE massive build up for a lame and terrible pun (or some other equally disappointing punchline). Except the punchline isn't really the entire punchline. It's three and a half fold: the sender is the willing butt of the joke spent the time telling the joke, the receiver the unwitting butt of the joke who wasted a huge amount of time receiving it, and then the punchline is a punchline in and of itself, but also in how disproportionate the build up is.I read the whole thing...talk about build up. Loved the punch line though.
