Paroles: The Simpsons. Baby On Board.

B-Sharps: Baby on board, how I've adored,
That sign on my car's windowpane
A bounce in my step; loaded with pep,
'Cause I'm driving in the carpool lane.

Call me a square; friend, I don't care
That little yellow sign can't be ignored
I'm telling you it's mighty nice
Each trip's a trip to paradise
With my baby on board.
