How many legs…?

A college graduate tells me that what she remembers from a math class for non-majors (that is, math for students whose talents lie elsewhere) is a question her professor asked at the end of a quiz:

 

 

“How many legs does a cow have?”

 

 

 

Answer:  Six.  Two hind legs and forelegs in front.

By the way, they weren’t graded down for incorrect answers on that one.

Been there? Done that? Read the book? What do you think?
