Homeless People and Silvers

[mburbank]

Wierd Al is referenicing the Henney Youngman joke, "So I bit him".

I am referencing the jokes structure on the assumption that the joke is so well known at this point to be public domain. The reader is encouraged to expect the punchline they know and begin to experience disapointment over a hackneyed joke being told as if it's new. As they experience peaks, they realize the expectation has been thwarted. Then the anticiapted some alternate punchline (see Wierd Al) and again, expectation is thwarted as there is no punchline, depsite the seeming structural requirement called for by the opening line.

Thwarted expcttions are one of the principle psychological pillars on which comedy rests.
