"Baby on Board"

(Homer's Barbershop Quartet 9F21)

Baby on board
how I've adored
that sign on my car's windowpane,
bounce in my step
loaded with pep
'cause I'm drivin' in the carpool lane,
call me a square
friend, I don't care
that little yellow sign can't be ignored.
I'm tellin' you it's mighty nice
each trip's a trip to paradise
with my baby on board.
