Haven't been here for a long time. Glad I found this thread. I used to love to sing Mad Magazine parodies when I was a kid. They were almost all we had before weird al. One I really liked and it is still relavent today is a song I call the weatherman song. I can't remember if that is the original name or not. Here are the lyrics
Seventy six degrees is what we'll predict
with one hundred and ten degrees by the shore
To be followed by days and days
Of an air pollution haze. That is what we weathermen adore
We always play safe and say there's a chance of rain
Or we say partly cloudy partly clear
We use words like "maybe" "perhaps" and "possible"
Just in case, the weather changes here
We're predicting sunny weather on the coast of Spain
Who'll know if it is so here in the U. S.
In Pago Pago we can say there is a hurricane
Who has changed her name to Bess
Predicting weather is a rewarding job
Whether we're right or wrong we still know
Our jobs are quite safe and sound
While there's weather still around
Give three cheers for wind and sleet and snow.

There is a karaoke website where I sang the song. Check this out.
