There was a Salon song from the 70s about that.. and here are the words:
Plastic Justrite
by
Barb MacLeod (1973)
Tune: "Plastic Jesus," traditional.
C
Now Justrite's got a new device,
F
Superior design, economical price,
C G7
Construction unexcelled in quality;
C
It has an unadjustable water drip
F
A styrofoam felt and a plastic tip
C G7 C
And other blessings of technology.
Chorus:
C F
Plastic Justrite, plastic Justrite,
C G7
Melted on the front of my hard hat;
C
Shoulda known better than to go and trust you;
F
If I ever get out I will stomp and bust you;
C G7 C
Underneath by Jeep I'll squash you flat!
Sittin' in a cave as black as midnight,
Cause I got a brand new plastic Justrite
Oozing off the front of my hard hat.
The lamp was fine, it was workin' OK,
I was trucking down a virgin passageway
Then it belched and melted out and that was that.
