He Really Liked Flannel With Big Bore Arms.
If You Looked In His Closet, It Was All That You Saw.
He'd Dress Up On Sunday; A Body Looked Neat,
In A Green Leisure Suit With Wing Tips On His Feet.

An' I Hated The Music He Played In The Car,
It Was Hard To Believe He Called Those People Stars.
They'd Sing Through Their Noses Like They All Had Colds.
I Guess It's Hard To Be Cool When You're Forty Years Old.

An' I Was Fifteen And Real Hip With Long Hair,
An' I'd Ask My Momma: "Why's Daddy So Square?"
An' I Couldn't Believe All That He Didn't Know.
I Guess It's Hard To Be Cool When You're Forty Years Old.

The Night I Turned Twenty, She Came With The News:
Scared Half To Death, An' Didn't Know What To Do.
I Told Her: "I'm Sorry, But It's Not Too Late.
"There's A Doctor I've Heard Of Who Fixes Mistakes."

An' I Thought He Was Workin', An' I Was Alone,
But He Was Standin' Behind Me When I Hung Up The 'phone.
He Said: "Son, There's A Few Things You Don't Know About.
"If You Listen Real Close, We Can Figure This Out."

"'Cause I Was Eighteen And As Wild As They Came,
"When One Night, A Young Girl Told Me The Same Thing.
"An' You Wouldn't Be Here If She Hadn't Said No:
"You See, It's Hard To Be Cool When You're Twenty Years Old."

These Days I Like Flannel An' Old Levi Jeans.
An' I Look At My Young Boy, Who Just Turned Fifteen.
An' I Know What He's Thinkin', But It's O.k., You Know.
You See It's Hard To Be Cool When You're Fifteen Years Old.
