The hood ornament for the duck truck was once a diesel engine piston. Beneath the duck is a thin white horizontal strip .... a rubber logo strip from an Electrolux vacuum cleaner. Electrolux rhymes with duck. What the Electrolux does also rhymes with duck. There is a discernable Chevrolet emblem .... I prefer to think of it as a "plus" symbol.
Some say it is an S 10 .... pronounced S.... Ten ....
However, as Dave points out, Zero is another name for "duck"
Thus S10 is really "It's one duck" ....... S one zero....
By the way, the answer to Old MAcdonald's FArm is ....... DUCK!
e times i times e times i times zero is DUCK ..... zero
If people spent more time thinking about ducks, They'd spend less time thinking about other things,
