If this is the only tMG song you know, I highly recommend checking out the rest of the album (Tallahassee). Fantastic album from front to back.

Some personal favorites (other than No Children):

Southwood Plantation Road

Our conversations are like minefields; no one's found a safe way through one yet.

Game Shows Touch Our Lives

People say friends don't destroy one another. What do they know about friends?

See America Right

My love is like a dark cloud full of rain that's always right there up above you.

Old College Try

I want to say I'm sorry for stuff I haven't done yet. Things will shortly get completely out of hand.

Oceanographer's Choice

Everybody's gonna need a witness. Everybody's gonna need a little backup in case the scene gets nasty.

Alpha Rats Nest

Someday we'll both wake up for good; I will try hard not to scream.

Also highly recommend checking out the albums We Shall All Be Healed, The Sunset Tree, and,if you're ok with lo-fi, All Hail West Texas and Songs for Pierre Chuvin.
