Mary had a little car, It's body was built of tin; She equipped it with Superior Plugs Which made it run like sin.
She drove the car to school one day, It bounded every step; The critter like to get away It was so full of pep.
What makes the car so active? The eager scholars cried. Why that's Superiority The teachers all replied.
Now folks if your car is lazy And spits and groans and lugs, You can make it run like Mary's If you'll use Superior Plugs.
- verse from an early Superior Spark Plugs advertisement
