Extreme - Waiting For The Punchline

You might say hey, I lost my sense of humor
Im quite surprised I didnt lose it sooner
Why waste your breath on anything less
Then talk so trivial
As a man who ran out of material
Chorus:
Why did the chicken go across the road
To get to the other side
Im still waiting for the punchline
Whoever said the grass always grows
Greener on the other lied
Im still waiting for the punchline
The good ol days I was known to wear a smile
