Cover art for Particle Man lyrics by They Might Be Giants

Person man = Clearly talking about humanity

"hit on the head with a frying pan"

-our heads are round, hinting what the author is talking about

"lives his life in a garbage can"

-we live our lives in our own trash

"is he depressed or is he a mess? does he feel totally worthless?"

-welcome to the feelings experienced by almost every human. "feeling worthless" is particularly relevant to the song as it is focusing on all the perspectives of the universe. It's easy to feel worthless when we compare ourselves to universe man.

"who came up with person man? degraded man, person man"

-once again looking at humanity's perspective on the universe. Asking who came up with person man is clearly our questioning of where we came from (ie. God)

Particle Man = represents particles, atoms, etc...kind of feel this represents science.

Triangle man = The church, religion. Putting down science. Putting down and controlling and subjugating the average person. Religion, our own construct, beats science and also beats humanity.

Universe man = The universe. Its the formulation of all time, from minutes to eons.

"He's got a watch with a minute hand millennium hand and an eon hand when they meet it's a happy land"

-When all of these hands meet, it will be the end of time.
