Cover art for Birds Fly lyrics by They Might Be Giants

ah, i forgot: "words fall out from my pockets" either a cat caught this man's tongue, or more likely, he rambles randomly with poor excuses and alibies under the police investigation. the cats dancing under his feet may be the police questioning him or investigating the situation in depth. (police man's act to investigate = cat's act of being curious) "this colorful spell under which I live protects me from all i write." its fitting that this is in the same verse as "words fall out of my pockets". perhaps the narrator realizes his mistakes of saying too much and now he is using the colorful spell which protects him- the fifth amendmen.
