The World's Most Self-Defeating Frasier End Credits Sequence

I've already spoken at great length about what is, to me, the absolute weirdest end credits sequence in the history of Frasier, so let's take a quick look at one which irritates the living snot out of me - that of "The Unnatural" of Season 4.  Here's an example of a closing gag that flounders because a tiny element in the presentation of the sequence manages to trip up the entire punchline.

Broadly, the episode deals with Frasier's anxieties that his son Frederick is on the verge of discovering that his father isn't perfect, but mixed in with all that we also learn of a harrowing incident from Roz's history.  As per Frasier's description: "I do recall a story you told me not long ago, about a young girl living in Wisconsin who wanted desperately for her mother to drive her to Chicago to see Bobby Sherman open a shopping mall.  But her mother was just too busy.  And so what did that little girl do that night? She cried herself to sleep on her little Bobby Sherman pillow."

Roz's childhood Bobby Sherman obsession is the subject of a mere one-off joke within the episode itself, but the end-credits sequence really capitalises upon it by having Frasier appease Roz with an array of Bobby Sherman-themed merchandise.  First he pulls out a Sherman LP, followed by a t-shirt, as all the while Roz becomes ever-more ecstatic.  Finally, Frasier steps out of the studio and returns with none other than Bobby Sherman himself, live and in the flesh.  Bobby, who clearly had no idea what he was getting into, is understandably startled at the sight of Roz, now in full teenybopper mode, and turns to Frasier for assistance, but he's already making a speedy exit from the studio, leaving Bobby at the mercy of the hysterical Roz.  End of sequence.

But Scampy, you say, isn't that actually a really hilarious punchline?  Why on earth are you being so down on it?  And true, I'm sure it seemed absolutely hilarious in rough cut form, but there's a reason why it flat-out doesn't work in the finished episode - namely, because the end credits spoil Bobby Sherman's cameo a good eight seconds before he actually shows up.  If you've just watched the entire episode, you'll know that Bobby Sherman has yet to appear, making it painfully obvious where the joke in-progress is headed.

This is a great example of a situation where an uncredited cameo might have worked wonders.  Perhaps they just weren't confident enough that people would believe that they'd gotten hold of the real Bobby Sherman.  Or maybe they were banking on the assumption that most viewers would be too invested in the sequence itself to even notice silly little things like cast credits.  I can't speak for anyone else, but personally my gaze could never help but wander downward whenever Frasier flashed that up t-shirt, my senses heightened to the fact that those exact same words were positioned right beneath it.  The episode as a whole I'm rather fond of, but dang, the hamfistedness here never fails to make me wince.
