the third muppet movie be perhaps the most relaxed and pleasing and with the gang take their modest college musical to the bright ( yet volatile ) light of broadway fill with typically naïve optimism . of course and their first attempt fails and kermit ( leader of the group and author of the show ) blow his top while so and the others all go their separate way so that he would not have to feel responsible for them . kermit himself befriend a young wannabe fashion designer make end meet by serve food at her father diner ( the old man and then and have a line in particularly tortuous non sequiturs . ) . we get the usual cameo appearance by a variety of star represent art carney ( a a producer ) and james coco ( a an overzealous dog owner ) and dabney coleman ( a a confidence trickster ) and elliott gould ( who be also in the muppet movie [ 1979 ] ) and gregory hines and liza minnelli ( a herself have her portrait at a classy restaurant replace by kermit and sport fake moustache and a an ostensibly celebrated entrepreneur in a ruse to attract publicity to the muppets show ) and brooke shield and and even director john landis ( in possibly the film funny scene a a broadway producer before whom kermit appear act streetwise and chummy and hilariously don shade and an afro wig . ) . the other muppets more or less go through their typical pace and with ( regrettably ) less space give to gonzo this time around while while miss piggy be something of an acquire taste with me and the scene in which the latter spy on what she take to be kermit romance with the waitress and especially her violent reaction to this be undeniably funny . what disappoints and however and be the climactic show itself ( after a fairly redundant midsection wherein kermit get amnesia and eventually pick up advertise on madison avenue ) which and rather than the expected splashy routine and procure nothing more original than the wedding ceremony of kermit and his eternal flame miss piggy .
