I've lost track of whether this has been mentioned before, but Mad did a take-off on West Side Story, called "East Side Story" - it was about the United Nations (whose headquarters are on New York's East side?)

One song (to the tune of "There's a Place for Us") was sung by Chairman Mao, asking to be admitted to the UN. One verse went something like

Please be sweet to us
and give a seat to us.
Let us in and such joy you'll get
like we gave
Tibet.
